Atul<issue_comment>username_1: I think there is no in built command, create a local clone remove the git folder, create empty repo & copy the folder & push.
Upvotes: 0 <issue_comment>username_2: Some options:
* Clone the repo with `git clone --depth=1` (which only clones the most recent commit), then add a new remote and push.
* If you're staying within your VSTS account, you can *[fork](https://learn.microsoft.com/en-us/vsts/git/concepts/forks)* the repo.

```
for s in list:
print(*s)
```
but it displays the list output as
```
['this is']
['the output']
```
But I would like the output to be displayed as
```
this is
the output
```
There should be a simple solution but i am still yet to come across one.<issue_comment>username_1: `list_string = ', '.join(list_name)`
`print (list_string) #without brackets`

```
print("\n".join(your_list))
```
Please note that `list` is a Python type and shouldn't be used as a variable name.

It's `checksetup.pl` passes, but the website returns 'Internal Server Error'.
The only thing in apache's error\_log is:
>
> /var/www/html/bugzilla/.htaccess: Options not allowed here
>
>
>
How should I approach fixing this?<issue_comment>username_1: Add 'Options' to AllowOverride in /etc/httpd/conf.d/buzilla.conf, and restart Apache.
Upvotes: 1 <issue_comment>username_2: "Require" is a type of AuthConfig directives. You need to specify, in httpd.conf, that type of directives are allowed in .htaccess. (
See <https://httpd.apache.org/docs/2.4/mod/core.html#allowoverride> and <https://httpd.apache.org/docs/2.4/mod/overrides.html#override-indexes>)
```
AddHandler cgi-script .cgi
Options +Indexes +ExecCGI
DirectoryIndex index.cgi
AllowOverride Limit AuthConfig Options Indexes FileInfo
```
The instructions from bugzilla does not have **AuthConfig** and the rest of the line here. You need to add them all in order to make /var/www/html/bugzilla/.htaccess acceptable to apache.

Upvotes: 3 [selected_answer]<issue_comment>username_4: Maybe this concept can help you..
You can use @ionic-native/network
To check current network connection inside the device
```
isConnected(): boolean {
let conntype = this.network.type;
return conntype && conntype !== 'unknown' && conntype !== 'none';
}
```
There is a function like `onConnect` and `onDisconnect` inside the `ionic-native/network` modules, but it only checks whenever you connect/disconnect the network from your phone when you were in-app. and maybe its useful to use the function if someone suddenly has no /disable the network connection
Constructor :
```
constructor(private network: Network, private toast: ToastController) { }
```
Simply put in the constructor
```
if(!this.isConnected()) {
this.openToast(this.isConnected());
}
```
Simply put inside the constructor of the page, This is how we can automatically check the network connection after the page is loaded
openToast() function
```
openToast(isConnected: boolean) {
let networkType = this.network.type;
this.toast.create({
message: `Network type: ${networkType} and ${isConnected}`,
duration: 3000
}).present();
}
```
and take note that in ionic 3.. The supported version of `@ionic-native/network` < 5.0.0
I tested on Ionic 3 can use version 4.6.0
This is how we declare `import { Network } from '@ionic-native/network/index';`
More info :
<https://www.npmjs.com/package/@ionic-native/network>
>
> Result : if the user open up the page with no internet connection,
> it's toast up a message

```
Intent intent = new Intent().setClass(v.getContext(), WinnerDetailActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
v.getContext().startActivity(intent);
((Activity)context).finish();
```
But when I click the back button, it doesn't go to the back activity.
What am I doing wrong?<issue_comment>username_1: Just remove this line:
```
((Activity)context).finish();
```
Upvotes: 0 <issue_comment>username_2: Called the Finish method of activity at button click.
finish() just lets the system know that the programmer wants the current Activity to be finished.
`((Activity)context).finish();`
Upvotes: 0 <issue_comment>username_3: Basically you should remove `finish()` method from your code so that it will not destroy that activity and keep it in stack.
Once you call the [finish()](https://developer.android.com/reference/android/app/Activity.html#finish()) you can not go back to previous activity. [This question](https://stackoverflow.com/questions/10847526/what-exactly-activity-finish-method-is-doing) explains in details, what happens when you call `finish()` method.
Upvotes: 2 <issue_comment>username_4: That is because you are finishing your activity which means when you press back you don't have any activity on your stack to go back to.
so just remove finish so that i will push WinnerDetailActivity on top of your current activity and on back of WinnerDetailActivity it will open your current activity.
```
Intent intent = new Intent().setClass(v.getContext(), WinnerDetailActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
v.getContext().startActivity(intent);

because
here you are **finishing your activity** which means when you press back you don't have any activity on your stack to go back to.
**Finish()** method will destroy the current activity. You can use this method in cases when you dont want this activity to load again and again when the user presses back button. Basically it clears the activity from the current stack.
So,no need to use **finish()** here

Method 1:
Whenever you're stating a New Activity from an Activity, Make sure that you don't call `finish()`. Calling `finish()` will destroy the Previous Activity in the Stack.
Next Method is by Overriding `onBackPressed()`, by doing so you can navigate to the desired Activity.

@Override
public void onBackPressed() {
super.onBackPressed();
Intent intent = new Intent( thisActivity.this, yourFirstActivity.class);
startActivity(intent);

2018/03/20 | 787 | 3,082 | <issue_start>username_0: I have a basic component that contains the `ngxPermissionsOnly` directive which is working as expected. The library is on github [here](https://github.com/AlexKhymenko/ngx-permissions). I generated the component using the @angular-cli which also auto-generated the unit test.
e.g. Component
```
@Component({
selector: 'project-card',
template: 'Hide Me'
styleUrls: ['./project-card.component.scss']
})
export class ProjectCardComponent implements OnInit {
//Do some stuff here
}
```
e.g. Test
```
describe('ProjectCardComponent', () => {
let component: ProjectCardComponent;
let fixture: ComponentFixture;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [
ProjectCardComponent,
]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(ProjectCardComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
expect(component).toBeTruthy();
});
});
```
When I run the test I get the below error;
```
Can't bind to 'ngxPermissionsOnly' since it isn't a known property of 'div'
```
I tried adding the `NgxPermissionsDirective` to the `TestBed` declarations, however this directive is dependent on services from that library, and I would also have to inject them. I also tried importing the `NgxPermissionsModule` itself but it has it's own errors. It seems counter-intuitive to inject a whole bunch of services to test a simple component. Is there a way to mock this directive? Or another solution?<issue_comment>username_1: I think you can just create mocked/stub directive by the same name in the test file and declare that in your test.
Or alternatively you could use CUSTOM\_ELEMENTS\_SCHEMA or NO\_ERRORS\_SCHEMA (more info [here](https://medium.com/@cnunciato/both-custom-elements-schema-and-no-errors-schema-have-been-mentioned-as-options-for-ignoring-the-f9ea78999cbe)) as a schema in your tests:
```
import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
describe('ProjectCardComponent', () => {
let component: ProjectCardComponent;
let fixture: ComponentFixture;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [
ProjectCardComponent,
],
schemas: [CUSTOM\_ELEMENTS\_SCHEMA]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(ProjectCardComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
expect(component).toBeTruthy();
});
});
```
This will skip the unknown properties in your DOM, but this shouldn't be used if you want to actually test how the directive works with your component.

I had table:
```
ID | Year | Month | Multiply | Future | Current
123 | 2017 | 1 | 1.0 | 25 | null
123 | 2017 | 2 | 1.0 | 19 | 15
123 | 2017 | 3 | 1.0 | 13 | 0
123 | 2017 | 4 | 1.0 | 22 | 14
123 | 2017 | 5 | 1.0 | 13 | null
... | .... | ... | ... | .. | ..
123 | 2018 | 1 | 1.0 | 25 | 10
123 | 2018 | 2 | 1.0 | 25 | 10
... | .... | ... | ... | .. | ..
124 | 2017 | 1 | 1 | 10 | 5
124 | 2017 | 2 | 1 | 15 | 2
... | .... | ... | ... | .. | ..
124 | 2018 | 1 | 1 | 20 | 0
```
I build this view to concatenate Year + Month and make IF statement:
value in the new Value column I'm getting from Future and Current column - when the Current value is null get the Future value and multiply by Multiply, else get Current value and multiply by Multiply (even 0). Next to it I need to add a 'F' prefix when the value is got from Future column.
```
ID | Date | Value |
123 | 2017 - 1 | F25 |
123 | 2017 - 2 | 15 |
123 | 2017 - 3 | 0 |
.. | .. | .. |
```
Code for it:
```
SELECT ID = ID,
[Date] = [Date],
[Value] = [Value]
FROM ( SELECT ID,
cast([Year] as varchar(30)) + ' - ' + cast([Month]as varchar(30)) as [Date],
[Multiply],
case when [Current] IS NULL /*OR [Current] = 0*/
then 'F' + CAST([Future] * [Multiply] as varchar(30))
else CAST([Current] * [Multiply] as varchar(30))
end as Value
FROM dbo.CurrentFuture
) AS t
```
And from this I make this view via dynamically pivot.
```

As you can see columns in the new view are not sorting in a good way.. instead of 2017 - 1, 2017 - 2, 2017 - 3 I have 2017 - 1, 2017 - 10, 2017 - 11, 2017 - 12, 2017 - 2. Can you help me how to sort it properly?<issue_comment>username_1: From the limited information, What you want is the ordering of the column based on the Concatenated string of Year+ Month.
What you need is to prefix the month with "0" for January - September and no prefix for October-December.
so in effect you will achieve this.
```
ID | 2017 - 01 | 2017 - 02 | 2017 - 03 | ..... | 2017 - 09 |2018 - 10 |2018 - 11||2018 - 12|
SELECT ID = ID,
[Date] = [Date],
[Value] = [Value]
FROM
(
SELECT ID,
CAST([Year] AS VARCHAR(30))+' - '+RIGHT('0'+CAST([Month] AS VARCHAR(30)), 2) AS [Date],
[Multiply],
CASE
WHEN [Current] IS NULL
/*OR [Current] = 0*/
THEN 'F'+CAST([Future] * [Multiply] AS VARCHAR(30))
ELSE CAST([Current] * [Multiply] AS VARCHAR(30))
END AS Value
FROM dbo.CurrentFuture
) AS t;

```
cast([Year] as varchar(30)) + RIGHT('0' + cast([Month] as varchar(30)), 2) as [DateOrder]
```
and use this column for sorting at your column query instead of [Date]
```
select @cols = STUFF((SELECT ',' + QUOTENAME([Date])

group by [Date], [DateOrder]
order by [DateOrder]

```
$newdata['rules']=[];
foreach ($data as $key => $value) {
if (substr($key,0,6)=='rules_') {
// split key using '_'
$parts = explode('_',$key);
// get the 'name'
$name = $parts[1] ;
// get the index (-1 to be 0 based)
$idx = $parts[2] - 1;
// store data in new array
$newdata['rules'][$idx][$name] = $value;
}
}
print_r($newdata);

Outputs:
```

Code: ([Demo](https://3v4l.org/sSLY0))
```
$data = (object)[
"class" => "srt-fields",
"rules_field_1" => "1",
"rules_condition_1" => "0",
"rules_value_1" => "text",
"rules_field_2" => "3",
"rules_condition_2" => "1",
"rules_value_2" => "another_text"
];
foreach ($data as $key => $value) {
$bits = explode('_',$key); // this will produce a 1-element array from `class` and a 3-element array from others
if (isset($bits[2])) { // if element [2] exists, then process the qualifying data
$newdata[$bits[0]][$bits[2]-1][$bits[1]] = $value;
// ^^- make zero based
}
}
var_export($newdata);
```
Output:
```
array (
'rules' =>
array (
0 =>
array (
'field' => '1',
'condition' => '0',
'value' => 'text',
),
1 =>
array (
'field' => '3',
'condition' => '1',
'value' => 'another_text',
),
),
)
```
I am using `-1` to make the output keys resemble a zero-based / indexed array. If your fields might not be consecutively ordered, you can remove the `-1` and write `$newdata['rules'] = array_values($newdata['rules']);` after the loop.

1. Using Push Notification to notify you application when there is a new piece of data. This will help sync data in real-time.
2. Your database and the server database should have some sign to detect if there is a new record. For instance, you can use an increment id, if the local id is smaller than the server's one, it is time to retrieve updated data.This will help sync data when users are off for a long time and then use the app again.

Well, there can be 2 mechanism for your app to know if there is new data which you need to fetch from the remote server and save to local `sqlite` database. Either `Push` or `Poll`.
Now, which one to use would depend on the situation.
**Polling** - Lets say user is looking a list of items. The users pulls to refresh, then you might choose to make a call to server to check if there is any new data. Or you may choose to continuously poll for new data continuously, which might not be a great idea since it might consume resources which is unnecessary.
**Pushing** - When server has a new data, then it can send an [FCM push notification](https://firebase.google.com/docs/cloud-messaging/) with the appropriate data. You can handle the push notification in your app and update the database with the new data. For example, if you have one table only in your local db, you would have unique Id's for each row. You can include the `id` and other relevant information in the FCM message and update the corresponding row in your local db.

While I want this bottom area to be "safe", I'd like the user to be able to see the content behind it, otherwise, the space is wasted.
How do I implement a "transparent" safe area?

return (

);
}
}
```
**Output:**
**Desired Output:**
<issue_comment>username_1: You could try react-navigation's SafeAreaView. Just set it's `forceInset` prop to `{ bottom: 'never' }` and you'll see it behaves as your expectation.
Example: <https://github.com/react-navigation/react-navigation/blob/master/examples/SafeAreaExample/App.js>
Upvotes: 1 <issue_comment>username_2: In most you do not want to have your `ScrollView/FlatList` have as a descendant of a `SafeAreaView`. Instead you only want to wrap your `Header` and `TabBar` into a `SafeAreaView`. Some examples:
Instead of this (WRONG EXAMPLE)
```js
```
you only wrap the header
```js
```
Also even if you do not really have a Header, you only want to avoid drawing behind the status bar, you can use the `SafeAreaView` as padding.
```js
// <- Now anything after this gonna be rendered after the safe zone
```

Use this in scrollView
Upvotes: -1 <issue_comment>username_4: In `ScrollView`, `contentInsetAdjustmentBehavior` controls inserting this safe area padding. Just set it as `automatic`
```
```

Docs:
```
/**
* This property specifies how the safe area insets are used to modify the content area of the scroll view.
* The default value of this property must be 'automatic'. But the default value is 'never' until [email protected].
*/
contentInsetAdjustmentBehavior?: 'automatic' | 'scrollableAxes' | 'never' | 'always';

Well, even on 0.64 I had to set it manually. Whatever is up with that.

Use `System.Xml.Serialization` Namespace
Classes:
```
[XmlRoot(ElementName="key")]
public class Key {
[XmlAttribute(AttributeName="name")]
public string Name { get; set; }
[XmlText]
public string Text { get; set; }
}
[XmlRoot(ElementName="settings")]
public class Settings {
[XmlElement(ElementName="key")]
public Key Key { get; set; }
}
```
And then something like this:
```
var path = "path to your xml";
var serializer = new XmlSerializer(typeof(Settings[]));
var reader = new StreamReader(path);
reader.ReadToEnd();
var settings = (Settings[])serializer.Deserialize(reader);
reader.Close();
return settings;
```
Try and check if this works.

string boolStr = doc.Root.Elements()
.Where(e => e.Name.LocalName == "key" && e.Attribute("name").Value == "setting_name" )

The native `filter` method is more appropriate.
I recommend to decode the JSON
```
let jsonString = """
{
"Data": [
{"id": "c9967156ad8945fba8cc482cd8aad900", "description": "Hi", "dateCreated": "2018-03-20T06:15:11.000+0000"},

]
}
"""
```
into custom structs
```
struct Root : Decodable {
private enum CodingKeys : String, CodingKey { case items = "Data" }
let items : [Item]
}
struct Item : Decodable {
let id, description : String
let dateCreated : Date
}
```
The decoder uses a custom date formatter to decode the ISO8601 date properly
```
let data = Data(jsonString.utf8)
let decoder = JSONDecoder()
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SZ"
decoder.dateDecodingStrategy = .formatted(dateFormatter)
do {
let result = try decoder.decode(Root.self, from: data)
```
The array is in `result.items`. Now you can `filter` the array by a specific date. In this example the reference date is created hard-coded with `DateComponents`.
```
let components = DateComponents(timeZone: TimeZone(secondsFromGMT: 0), year:2018, month:03, day:16, hour:17, minute:8, second:7)
let date = Calendar.current.date(from: components)!
let filteredItems = result.items.filter { $0.dateCreated == date }
print(filteredItems)
} catch { print(error) }
```
If you want to find all matching records for a given date in the array use a loop
```
for item in result.items {
let filteredItems = result.items.filter { $0.dateCreated == item.dateCreated }
if filteredItems.count > 1 { print(filteredItems) }
}
```

2018/03/20 | 582 | 1,855 | <issue_start>username_0: I'm new to programming and currently learning C from The C Programming Language by <NAME> and <NAME>. I have a difficult at section 1.8. Why when I'm trying to change
```
for (i = 1; n > 0; --n)
```
into
```
for (i = 1; n > 0; ++n)
```
the output is,
```
0 1 1
1 2 3
2 2 3
3 2 3
4 2 3
5 2 3
6 2 3
7 2 3
8 2 3
9 2 3
```
Why this is happen?
Here is the full code,
```
#include
int power(int m, int n);
main(){
int i;
for (i = 0; i < 10; ++i)
printf("%d %7d %7d\n", i, power(2,i), power(3,i));
return 0;
}
int power(int base, int n){
int p;
for ( p = 1; n > 0; --n)
p = p \* base;
return p;
}
```<issue_comment>username_1: In the power methods' for-loop you decrement n until in some iteration of the loop n is zero (no longer n > 0). If you now change the loop to increment n every iteration, n will continue growing until you get an integer overflow ([Wikipedia: Integer overflow](https://en.wikipedia.org/wiki/Integer_overflow)) and n becomes negative at which point your program will terminate.
Upvotes: 0 <issue_comment>username_2: the syntax of for loop is
```
for (initialization expr; test expr; update expr)
```
which means, the first expression will be executed once,
the test expression is checked every time for ture or false every time the loop starts, and update expression is evaluated unconditionally on every time loop start.
in this case, n-- is evaluated before checking n > 0, which means the loop will stop when n becomes 0. but if you change it to n++, n will keep on increasing every time of the loop, until the integer is overflowed.
you can change the loop to the following to get output:
```
for (i = 1; i <= n; ++i)
```

I want to open the next `Activity` which is `Results.kt`.
Here is what I've tried so far:
```
if (Beats != 0) {
var intent = Intent(this, Results::class.java)
ContextCompat.startActivity(intent)
}
```<issue_comment>username_1: You can not use `this` as it's not an `Activity` and therefore not a `Context`. You have to provide a proper `Context` and can also pass flag saying new task:
```
if (Beats != 0) {
var intent = Intent(MyClass.this.context, Results::class.java)
MyClass.this.context.startActivity(intent)
}
```
Here replace `MyClass` with your class name. Not sure if it will work or not.
Upvotes: 0 <issue_comment>username_2: As long as you have a proper `Context` available, you can start your `Results` as follow:
```
if (Beats != 0) {
var intent = Intent(context, Results::class.java)
context.startActivity(intent)
}
```
If your non-activity class does not have access to a `Context` right now, you should inject it somewhere (during creation of your object as a passed-in argument for example).

When I try to publish that to end users, I can still ask people to use `npm install` > `npm start` to use the package. However, it doesn't sound decent.
How can I make people being able to use:
```
npm install myPackage
myPackage start
```
to start the server and then they can open localhost: 3000 directly?<issue_comment>username_1: You need to create global package for your module so that it can be installed
```
npm i -g module
```
then provide some config file like gulpfile.js which will be used by your package to carry out the task to start server any other task
Upvotes: 0 <issue_comment>username_2: You can make a global module and attach it to a bin command.
[Here's the tutorial for that by npm itself](http://blog.npmjs.org/post/118810260230/building-a-simple-command-line-tool-with-npm).
In your package.json file, you can add this:
```
"bin": {
"your-command": "bin/path/to/js/file.js"
}
```
and then whenever the user installs your module globally, then they can directly type in that command and the js file will execute your code.

Simply, I want everything in my layout (buttons, imageViews, Background, textViews, textEdits) to stay in place when soft keyboard is shown. I do not care about what it will cover.
I tried all of the following and all produced the same output and do not work:
1. (did not work) I tried writing `android:windowSoftInputMode="adjustNothing"` in my `AndroidManifest.xml`
2. (did not work) I tried writing `getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);`in my`onCreate()` though it did not work
3. I tried writing `android:windowSoftInputMode="adjustResize"`
in my `AndroidManifest.xml` and also did not work
4. (did not work) I tried writing `android:windowSoftInputMode="stateHidden|adjustPan"` in my `AndroidManifest.xml`
5. (did not work) I also tried writing `android:windowSoftInputMode="stateVisible|adjustPan"` in my `AndroidManifest.xml`
All the above solutions produced the following snapshot:
The actual layout looks like this (this is what I want it to keep looking when soft keyboard is active):
Any idea of how to prevent this?
This is my AndroidManifest.xml
```
xml version="1.0" encoding="utf-8"?
```
MainActivity.xml
```
```<issue_comment>username_1: This work for me

While staying in one Activity, sometimes the soft keyboard would cause re-layouts and sometimes it wouldn't, depending on what Fragment I had loaded. Finally I figured it out. It was caused by a RecyclerView being visible:
```
```
That's it. If the Fragment I had loaded had a visible RecyclerView, the soft keyboard would cause re-layout. If not, it wouldn't. It even causes a re-layout of stuff that isn't part of the Fragment that contains the RecyclerView.
That's how it looks in a ConstraintLayout. But it could also be in a RelativeLayout. If its visibility is "gone", the soft keyboard's appearance doesn't cause re-layout. If it's "visible", the soft keyboard's appearance causes a re-layout of the whole Activity. I don't know what versions of Android this "works" on, and I don't know whether it's intentional.
I know you don't have one, but maybe something else in your .xml does the same thing, or has a RecyclerView in it. I'd surmise that the presence of the RecyclerView causes the SoftInputMode to be set. You could consider waiting for your view to finish laying out, then changing SoftInputMode, and see if it sticks.

You can simply write a function triggered on click of button that opens the popup as of now and submit the form.
After submission, you can continue your function to open a popup for **"Device found or not found"**
For example:
```
This is my popup
================
.myPopup {
display: none;
position: fixed;
top: 0px;
bottom: 0px;
top: 0px;
bottom: 0px;
margin: auto;
border: 1px solid black;
border-radius: 5px;
height: 500px;
width: 500px;
}
.showPopup {
display: inline-block;
}
```
`Discover`
```
function submitForm() {
var hi=document.createElement('input');
hi.type='hidden'; hi.name='action'; hi.value='Discover';
settings_form.appendChild(hi);
settings_form.submit();
}
settings_form[0].addEventListener("submit", function() {
document.getElementsByClassName("myPopup")[0].classList.add("showPopup");
});
```

2018/03/20 | 692 | 2,113 | <issue_start>username_0: I'm trying to write a simple logger using variadic templates for my understanding. It works, but with a catch.
```
void log() {
std::cout << std::endl;
}
// variadic Template
template
void log(T t1, Args... args) {
std::cout << t1<<" ";
log(args...);
}
int main()
{
log("Logging", 1, 2, 3.2, 4);
return 0;
}
```
This is not outputting the last parameter `'4'` in the console. The output for this is
`Logging 1 2 3.2`
When I debugged, it's not entering the 'empty' log function at all. In fact, it compiles and gives the same output without that empty `log()` function.
Can someone please explain why this is behaving that way?<issue_comment>username_1: In Visual Studio is it better to use namespace for similar with std function names
In global namespace call of `log(4)` evaluates to macro `_GENERIC_MATH1(log, _CRTDEFAULT)` defined in `xtgmath.h`
[](https://i.stack.imgur.com/CJSlQ.png)
```
#include // - this indirectly includes macro \_GENERIC\_MATH1 from ^^^^^^^
namespace mylog{
void log() {}
// variadic Template
template
void log(T t1, Args... args)
{
std::cout << t1 << " ";
log(args...); // calling log with parameter pack
// but the last call is log(4)
// which is calling macro \_GENERIC\_MATH1 in global namespace
}
}
int main()
{
mylog::log("Logging", 1, 2, 3.2, 4);
return 0;
}
```
For additional information have a look at the [username_2](https://stackoverflow.com/users/440558/some-programmer-dude) answer.
Upvotes: 2 <issue_comment>username_2: The problem is that Visual C++ pulls in [`std::log`](http://en.cppreference.com/w/cpp/numeric/math/log) into the global namespace.
Your chain of calls **should** be
```
log("Logging", 1, 2, 3.2, 4);
log(1, 2, 3.2, 4);
log(2, 3.2, 4);
log(3.2, 4);
log(4);
log();
```
The problem with Visual C++ is that the next to last call, `log(4)`, is really `std::log(4)`, which of course will not call your own `log` function.
The simplest solution is to rename your function as something else.

This means value will be read from objects property the same as set in optionLabel attribute and will show up when calling item.label or selectedItem.label.
Upvotes: 2 <issue_comment>username_4: Getting PrimeNG p-dropdown to work with array of strings is possible, though it is not well documented. I use it sometimes when selecting timezones. There might be cleaner options, but I use ng-template to populate the dropdown and onChange to store the selected string value:
**HTML**
```
{{item}}
{{item}}
```
**Component.ts**
```
portNames: string[] =["Port 01","Port 02", "Port 03"];
selectedPort="";
storeValue(event) {
console.log(event); //event.value will likely be undefined, check event.originalEvent
this.selectedPort = event.originalEvent.srcElement.innerText;
}
```

2018/03/20 | 1,026 | 4,149 | <issue_start>username_0: I am a beginner and I am making a simple android game in which a user sign in into the app and play the game. After the game finishes I want to add the current score of the user with previous score and then store this total score in Firebase and then again retrieve the score next time when the user plays game.
I am not getting on how should I save the Total score for every different user who sign in.
this is my firebase json tree
<https://drive.google.com/file/d/1T7-x3TP1TaA8_ntwfoRNdb2oMGV_swl6/view?usp=sharing>
```
private void updateScore() {
TotalScore = new Firebase("https://bscitquiz.firebaseio.com/Users/" + username +"/highScore");
TotalScore.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
Integer totalscore = dataSnapshot.getValue(Integer.class);
totalscore = totalscore + mScore;
dataSnapshot.getRef().setValue(totalscore);
HighScore.setText("" +totalscore);
}
@Override
public void onCancelled(FirebaseError firebaseError) {
}
});
}
```<issue_comment>username_1: You can have a path for score under User (for Eg: User/userId/score) where you can update the score each time after completing the game. Below is the javascript code.
```
firebase.database().ref('User').child(userId).child('score').set(currentScore).then(result => {
const user = snap.val()
const userKey = snap.key
}).catch (function(err) {
console.error(err)
})
```
Here currentScore is the value you want to update.
You can go through this link if you want it in android: <https://firebase.google.com/docs/database/android/read-and-write>
Upvotes: 0 <issue_comment>username_2: You can save each user's score under its name at the database and just update it each time.
the android java code is written like this -
```
public static void updateScore(Integer score, String userId) {
DatabaseReference ref = FirebaseDatabase.getInstance().getReference();
ref.child("Users").child(userId).addListenerForSingleValueEvent(new ValueEventListener() {
@Override public void onDataChange(DataSnapshot dataSnapshot) {
Integer previousScore = dataSnapshot.getValue(Integer.class);
if (previousScore != null){
previousScore = previousScore + score;
dataSnapshot.getRef().setValue(previousScore);
}
}
@Override public void onCancelled(DatabaseError databaseError) {
Log.e("frgrgr", "onCancelled", databaseError.toException());
}
});
}
```
This way you retrieve the old score, update it, and send back to the database.
Now at this way you have only the score value under each user.
You can use the user's name for the child ref of "Users" if its unique or just generate an Id for each user.
**Edit after understanding your need for a callback -**
[callback in android?](https://stackoverflow.com/questions/2566852/callback-in-android)
For adding a callback there are a few steps,
1. open a new java class with the following code -
```
public interface FireBaseCallbacks {
interface GetScoreCallback {
public void onGetScoreComplete(Integer score)
}
}
```
2. add the callback parameter to your updateScore method -
```
private void updateScore(FireBaseCallbacks.GetDevicesCallback callback) {
...
}
```
3. call the callback parameter after you get the value -
```
Integer totalscore = dataSnapshot.getValue(Integer.class);
callback.onGetScoreComplete(totalscore)
```
4. call the method somewhere in your activity (at the point that you want to update the score) with this as a parameter to tell the callback where to come back to (regarding the activity) -
```
updateScore(this)
```
5. now for the last step, implement the FireBaseCallbacks.GetScoreCallback to your activity and then you'll be forced to implement its onGetScoreComplete method. implement it and inside it you get the score as a parameter to do what ever you wish :)
Hope this will help, let me know otherwise.

You need to install the application from the website, but you MUST do so using the command-line like so:
```
wget https://release.gitkraken.com/linux/gitkraken-amd64.deb
sudo dpkg -i gitkraken-amd64.deb
```
If you try to install it by just double-clicking the .deb file in your home directory, it will not work as snap does some funky things with it.

2018/03/20 | 592 | 2,197 | <issue_start>username_0: I am working on a Code Receipt Number Auto Generate. Here is my code:
```
var conrecipt = new SqlConnection(
ConfigurationManager.ConnectionStrings["con"].ConnectionString);
conrecipt.Open();
var cmd = new SqlCommand("Select COALESCE(MAX(Reciptno),0) from Registration", conrecipt);
int i = Convert.ToInt32(cmd.ExecuteScalar());
conrecipt.Close();
i++;
Label3.Text = Reciptno + i.ToString();
```
It's working fine. But I need to check 3 tables : Registration, Advance and one more table and need to find max from those id's.
How can I do this in Asp.Net C# and MS SQL Server 2012?<issue_comment>username_1: You could use union for obtain all the reciptno and the select the max
```
select COALESCE(MAX(Reciptno),0)
from (
Select Reciptno
from Registration
UNION
Select Reciptno
from Advance
UNION
Select Reciptno
from one_more_table
) as t
```
AND If you have nvarchar you could use a convert
```
select COALESCE(MAX( convert (int, t.Reciptno)),0)
from (
Select Reciptno
from Registration
UNION
Select Reciptno
from Advance
UNION
Select Reciptno
from one_more_table
) as t
```
Upvotes: 2 <issue_comment>username_2: ```
SELECT MAX(M)
FROM
(
SELECT MAX(Value) as M Table1
UNION ALL
SELECT MAX(Value) as M Table2
UNION ALL
SELECT MAX(Value) as M Table3
) as x
```
And in general it is more correct to use a sequence for all three tables and there will be no problems with the definition of a new value
Upvotes: 2 <issue_comment>username_3: Use a stored procedure to implement the ID logic. In the stored proc you could find the IDs from all the relevant tables and calculate the maximum ID. You would then call the stored procedure from the app.
For an even better solution, have a read about entity relationship design. Receipt is an entity that should define receipts including its ID (primary key) in one place. If Receipt Id is used in other tables this is called a foreign key which should be enforced in the database ensuring that every ID referenced in a table already exists in the "master" receipt table.

I have been trying for days now. I tried **cleaning project, cleaning build folder, removing derived data, removing files in the watchOS DeviceSupport, restarting Xcode(9.2), restarting Apple Watch Simulator**
*(External Displays option does not shows Apple Watch Alternatives by the way)*
Can you help with the possibilities that might cause this issue?
What else should I try?
*Xcode does not launch my app on the watch simulator* :/ this is the summary of the issue.<issue_comment>username_1: On the iOS(iPhone) simulator launch the Apple "Apple Watch" app (not your app) scroll all the way down to the buttom, down there your app should have a loading icon next to it, wait 20 minutes if the icon haven't shown up on the watch, restart your computer, with the option to relaunch all apps ticked to off, launch xcode, then try the above mentioned.
Upvotes: 1 <issue_comment>username_2: When trying out my first watchOS app, I was seeing the same behaviour. I could not find the app's icon in the simulator. The following is what I did.
* I stopped the app in Xcode.
* Launched it again.
* This time I opened the main app in the iPhone simulator also.
* The icon for the app appeared in the watch simulator among other apps and the app launched.
* For ~10 seconds a loading indicator was shown.

Solution: assign `class="woocommerce"`
to the elementor widget that you are using to place the star rating. It could be the shortcode widget, html, text editor or anything crazy you are trying to do with elementor

```
...
```
Add dir="rtl" to the html tag any time the overall document direction is right-to-left. This sets the base direction for the whole document.
No dir attribute is needed for documents that have a base direction of left-to-right, since this is the default.
Here is one very nice article to achieve RTL in your HTML template : <https://www.w3.org/International/questions/qa-html-dir>

2018/03/20 | 684 | 2,291 | <issue_start>username_0: I know that if I want to check if an array does contain a certain value I should use `Arrays.asList(arrayName).contains(valueName)`.
But how do I check if that value is not present? At first I just thought of putting ! in front like:
```
!Arrays.asList(arrayName).contains(valueName)
```
but that doesn't seem to work.
I even tried writing the if statement like this:
```
if (Arrays.asList(arrayName).contains(valueName)==false)
```
but that doesn't seem to work either.
Here is the code:
```
public int[] duplikati(int[] tabela){
int len = tabela.length;
int c = 0;
int[] count = new int[len];
for (int i=0;i
```<issue_comment>username_1: You can use Java 8 stream api as follows
```
Integer arr[]=new Integer[]{1,2,30,61};
System.out.println(Arrays.asList(arr).stream().noneMatch(element>element==10));
```
You can go through the below link for explaination of
[noneMatch()](https://beginnersbook.com/2017/11/java-8-stream-nonematch-example/)
Upvotes: 0 <issue_comment>username_2: In, this specific case when you pass an array of primitive types into `Arrays.asList` you'll get back a List with a *single* element which is the provided array.
So, when you do:
```
Arrays.asList(arrayName).contains(valueName)
```
The call `Arrays.asList(arrayName)` will return a `List` and then when you call `contains` the `valueName` will get boxed to an `Integer` and then get's compared with the element(s) in the list. because an `int[]` is never equal to an integer value, the `contains` call will always return `false`.
Solution 1 - change the type of your arrays from `int[]` to `Integer[]`, then everything should work as you expect.
Solution 2 - Assuming you do not want to change the type of the arrays for some reason, then you can do:
```
final int index = i;
if(Arrays.stream(count).noneMatch(e -> e == tabela[index])){...}
```
inside the for loops.
You can think of the `noneMatch` method as `!Arrays.asList(someArray).contains(someValue)` if it helps.
Similarly, you can check if the array contains an element with:
```
final int index = i;
if(Arrays.stream(count).anyMatch(e -> e == tabela[index])){...}
```
You can think of the `anyMatch` method as `Arrays.asList(someArray).contains(someValue)` if it helps.

Because here, `c1.AppSettings` is an object, but `c1.AppSettings.Settings` contains not items (hence `0` Count). It is not really loading the `AppSettings` keys. When trying to read any `Key` from `Settings` collection, it gives this error.
Is there any way how to load `AppSettings` keys from a `web.config` file outside the application folder.
If I put same file within application folder, then it reads the keys successfully.
This is my sample config file's content:
```
xml version="1.0" encoding="utf-8"?

I have a web application already running on my server. And I need to develop a small utility which has to do some job in database, and I don't want to write db credentials or connection string(and some other additional app-settings) in each application, I want it to read same thing from web.config.<issue_comment>username_1: Read documentation: [ConfigurationManager.OpenExeConfiguration on MSDN](https://msdn.microsoft.com/en-us/library/ms224437(v=vs.110).aspx)

```
var filePath = @"C:\Users\Idrees\Downloads\New folder\Web.config";

var configuration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);

in above .config example connectionStrings is sourced from an other file. Below an example what can be such an external config file:

```
//When we create the "totals"
//add the property "material_id" to Total
material.materials.forEach(x => {
rows.push(this.fb.group({
...
}))
this.totals.push({amount:0,total:0,material_id:x.id}); //<--add the property material_id
})
//then, in the function setOnChange
setOnChange()
{
const formarray=this.myForm.get('rows') as FormArray;
for (let i=0;i{
//search the index of "material\_id"
let index=this.totals.findIndex(t=>t.material\_id==val.material\_id)
if(val.dis\_checkbox){
...
this.totals[index].amount=value; //<--NOT this.totals[i],
this.totals[index].total=values;

1.-Delete the totals[rowIndex]
2.-recalculate total
```
onDeleteRow(rowIndex) {
let rows = this.myForm.get('rows') as FormArray;
rows.removeAt(rowIndex);
this.totals.splice(rowIndex,1); //<--remove the totals[rowIndex]
this.total=this.totals.reduce((sum,item)=>sum+item.total,0); //<--recalculate total

2018/03/20 | 552 | 1,879 | <issue_start>username_0: I know a lot of people asked that already but nothing seems to work. I want my footer to be on the bottom of the page. So far it is on the bottom of the screen, but if the page is bigger and you need to scroll, it just sticks there and stays in the middle. If I put `position: fixed` the footer scrolls with you. I want it to be at the **VERY BOTTOM** of the page, though, so you have to scroll down to see it in the first place, if the page is too big.
I tried several different wrappers and pushers but nothing seems to work.<issue_comment>username_1: In OnDeleteRow you have:

2018/03/20 | 1,485 | 5,206 | <issue_start>username_0: I have this code:
```
public function taxesData(Product $product)
{
$taxes = \Auth::user()->taxes;
foreach ($taxes as $tax) {
echo "$product->getTax($tax)";
}
}
```
which on testing gives this error:
>
> Type error: Too few arguments to function App\Product::getTax(), 0 passed in E:\projects\ims\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Concerns\HasAttributes.php on line 411 and exactly 1 expected

However, just a small change makes it works, but I am not able to understand. Why?
```
public function taxesData(Product $product)
{
$taxes = \Auth::user()->taxes;
foreach ($taxes as $tax) {
echo $product->getTax($tax);
}
}
```
Please help.
I tried to simplify it for the purpose of posting here... actually i am creating json with html component for a datatable ->
```
public function taxesData(Product $product)
{
$taxes = \Auth::user()->taxes;
return datatables()
->of($taxes)
->addColumn('check',function($tax) use($product){
if($product->hasTax($tax)){
return "";
}else{
return "";
}
})
->editColumn('tax', function($tax) use($product){
return "
"
})
->toJson();
}
```
Adding getTax method
```
public function getTax(Tax $t)
{
if($this->hasTax($t)){
return $this->taxes->find($t->id)->pivot->tax;
}
else{
return $t->pivot->tax;
}
}
public function hasTax(Tax $tax)
{
foreach ($this->taxes as $t) {
if($t->id == $tax->id){
return true;
}
}
return false;
}
```<issue_comment>username_1: It fails because you are not following the correct syntax of echo strings.
This would work:
```
echo "{$product->getTax($tax)}";
```
or actually, because you dont' need the quotes for such a simple expression:
```
echo $product->getTax($tax);
```
Upvotes: 2 <issue_comment>username_2: Here's what I've done so far.
Just for simplicity, I've created a sample Model.
```
// SampleModel.php
public function relatedModels()
{
return $this->hasMany(RelatedModel::class);
}
// this is like an accessor, but since our model doesn't have
// a property called `relatedModels`, Laravel will ignore it
// until later...
public function getRelatedModels()
{
return "Sample";
}
```
Given the following code, here are the outputs.
```
$a = SampleModel::find($id);
$a->relatedModels;
// this returns a collection of related models to this model.
$a->getRelatedModels();
// this returns "Sample";
// HOWEVER, when we try to interpolate that member function call.
"$a->getRelatedModels()"
// this throws error that the method `getRelatedModels` must return a relationship.
// I've also tried to add an argument to my existing function to be in-line with your situation.
public function getRelatedModels($a) ...
// this works well
$a->getRelatedModels(1);
// but this, yes, it throws the error as same as what you've got.
"$a->getRelatedModels(1)";
```
The error pointed out this line in the framework's codebase.
```
// HasAttributes.php
protected function getRelationshipFromMethod($method)
{
$relation = $this->$method(); // <-- this line
```
For some reason, doing `"$a->getRelatedModels(1)"` triggers the `__get` magic method of the model.
Which branches down to this stack call.
```
// Model.php
public function __get($key)
{
return $this->getAttribute($key);
}
// |
// V
// HasAttributes.php
public function getAttribute($key)
{
...
return $this->getRelationValue($key);
}
// |
// V
// HasAttributes.php
public function getRelationValue($key)
{
...
if (method_exists($this, $key)) {
return $this->getRelationshipFromMethod($key);
}
}
// |
// V
// HasAttributes.php
protected function getRelationshipFromMethod($method)
{
$relation = $this->$method(); // <-- lastly to this
// $method = "getRelatedModels"
// since our method `getRelatedModels` needs an argument
// this call will fail since it wasn't able to provide an argument.
...
}
```
That's why you're getting the too few arguments passed exception. I want to investigate further but I have to go home!
I don't know if this is a legit bug for Laravel, but if you do think so, issue it on Laravel's github repository.
**UPDATE**
I've posted an issue in github and this is one of the comments which truly made sense for me.
This is neither a issue with Laravel, nor with PHP. You are just using the wrong syntax, see it here: <https://github.com/laravel/framework/issues/23639>
Github user *@staudenmeir* commented:
>
> `"$sampleModel->getRelatedModels()"` is equivalent to `"$sampleModel->getRelatedModels"."()"`.
>
>
> The usage of variables in strings is limited to `"$foo"` and `"$foo->bar"`. Function calls like `"$foo->bar()"`

>

So that is why the magic method `__get` is being called.

2018/03/20 | 609 | 2,407 | <issue_start>username_0: I have an int array with 1000 elements. I need to extract the size of various sub-populations within the array (How many are even, odd, greater than 500, etc..).
I could use a for loop and a bunch of if statements to try add to a counting variable for each matching item such as:
```
for(int i = 0; i < someArray.length i++) {
if(conditionA) sizeA++;
if(conditionB) sizeB++;
if(conditionC) sizeC++;
...
}
```
or I could do something more lazy such as:
```
Supplier ease = () -> Arrays.stream(someArray);
int sizeA = ease.get().filter(conditionA).toArray.length;
int sizeB = ease.get().filter(conditionB).toArray.length;
int sizeC = ease.get().filter(conditionC).toArray.length;
...
```
The benefit of doing it the second way seems to be limited to readability, but is there a massive hit on efficiency? Could it possibly be more efficient? I guess it boils down to is iterating through the array one time with 4 conditions always better than iterating through 4 times with one condition each time (assuming the conditions are independent). I am aware this particular example the second method has lots of additional method calls which I'm sure don't help efficiency any.<issue_comment>username_1: Extract business logic into separate method annotated by `@Transactional(rollbackFor = Exception.class)` and remove annotation from `saveKot`.

Anyway, if you can read and translate simple C code to Javascript, here is a link to 9 star pattern you could try
<http://cbasicprogram.blogspot.it/2012/03/star-patterns.html>
Star pattern algorithms are generally very simple to understand in every language since they are used as beginner exercises. If you don't find anything JS related, try and search in another language.

I'm almost certain this is a problem with stream IDs but I'm really new to the HTTP2 protocol so I'm actually not sure what's going wrong or why I'm getting the protocol error.<issue_comment>username_1: I would guess it is because you have not sent your Settings Frame - you have only acknowledged the server Settings Frame.
The spec [could be clearer on this](https://www.rfc-editor.org/rfc/rfc7540#section-6.5):
>
> A SETTINGS frame MUST be sent by both endpoints at the start of a connection

Does an acknowledgement Settings Frame count?
However [this section](https://www.rfc-editor.org/rfc/rfc7540#section-3.5) states:
>
> This sequence MUST be followed by a SETTINGS frame (Section 6.5), which MAY be empty.
> ...
> The SETTINGS frames received from a peer as part of the connection preface MUST be acknowledged (see Section 6.5.3) after sending the connection preface.

So I’m taking that as you must send your Settings Frame and then acknowledge the server Settings Frame.

2018/03/20 | 751 | 3,112 | <issue_start>username_0: I'm fairly new on using ConstraintLayout (java).
What I want to achieve is something like when the numpad is being shown/hidden as a slide animation, I've tried something like this:
```
Animation a = new Animation() {
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
ConstraintLayout.LayoutParams lparams = (ConstraintLayout.LayoutParams) guideline.getLayoutParams();
lparams.guidePercent = 0.5f;
guideline.setLayoutParams(lparams);
}
};
a.setDuration(3000);
a.setFillAfter(true);
guideline.startAnimation(a);
```
Yes, the guideline (and corresponding views that is attached to it) is being moved to the center of the screen but it is not as smooth as it is supposed to be. Is there a way to achieve the smoothness of the animation?
Any suggestion would be much appreciated!<issue_comment>username_1: You can use a `ValueAnimator`
Sample in Kotlin.
```
val guideline = findViewById(R.id.guideline2) as Guideline
val end = (guideline.layoutParams as ConstraintLayout.LayoutParams).guidePercent
// get end percent. start at 0
val valueAnimator = ValueAnimator.ofFloat(0f, end)
valueAnimator.duration = 3000
// set duration
valueAnimator.interpolator = AccelerateDecelerateInterpolator()
// set interpolator and updateListener to get the animated value
valueAnimator.addUpdateListener { valueAnimator ->
val lp = guideline.layoutParams as ConstraintLayout.LayoutParams
// get the float value
lp.guidePercent = valueAnimator.animatedValue as Float
// update layout params
guideline.layoutParams = lp
}
valueAnimator.start()
```
Java Version
```
final Guideline guideline = findViewById(R.id.guideline2) ;
ConstraintLayout.LayoutParams lp = (ConstraintLayout.LayoutParams)guideline.getLayoutParams();
float end =lp.guidePercent;
ValueAnimator valueAnimator = ValueAnimator.ofFloat(0f, end);
valueAnimator.setDuration(3000);
valueAnimator.setInterpolator(new AccelerateDecelerateInterpolator());
valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
ConstraintLayout.LayoutParams lp = (ConstraintLayout.LayoutParams)guideline.getLayoutParams();
lp.guidePercent = valueAnimator.getAnimatedFraction();
guideline.setLayoutParams(lp);
}
});

2018/03/20 | 532 | 2,083 | <issue_start>username_0: I have two `spannable` object for same string and both have different styles. I need to merge all `spannable` objects and display all styles into `TextView`.
From one of returning from `Html.fromHtml()` and second return StyleSpan(Bold).
I tried `TextUtils.concate(htmlSpan, boldSpan)` but it displayed same string two times because it append `spannable`, i want to display my all styles into single string.<issue_comment>username_1: Use `SpannableStringBuilder` but you can create spans inside the `append` method
```
SpannableStringBuilder sb = new SpannableStringBuilder();
sb.append(String.valueOf(Html.fromHtml(stringToConvert));
sb.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 0, sb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
```
And then just set `sb` to your view
```
textView.setText(sb);
```
**EDIT**:
I saw your edited question, Above I **rewrote this code** to get it to apply two spannables on one string. I think you cannot merge different spannable objects on one string. I believe a workaround would be to apply one span, then convert in to string and then apply the second span. This way it will apply two spans to one string. Or you can manage your bold text type via xml if you always need it in bold
Upvotes: 2 <issue_comment>username_2: Finally i found my solution, Html.fromHtml() not have spannable type parameter, so firstly i got SpannableStringBuilder from Html.fromHtml() and carry forward it into create Bold StyleSpannable method then set into TextView, and it works awesome.
It retain HTML spannable into bold StyleSpannable method.
Thanks guys for your feed back and response of my answer.
```
SpannableStringBuilder spannable = setTextViewHTML(content);
common.convertBoldString(spannable);
textView.setText(spannable);
```
For the above code content is a variable, which contain words which i like to bold and it also contain HTML tags.
`convertBoldString` is method in my Common methods class which has parameter
`SpannableStringBuilder` and this object use to set bold StyleSpan.

2018/03/20 | 842 | 2,953 | <issue_start>username_0: I have a class with a method which uses shutil.rmtree to remove some files if a param is passed as true, How to mock this behavior so as other tests don't break which needs these files.
My class looks like this -
```
class FileConverter(object):
def __init__(self, path_to_files):
self._path_to_files = path_to_files
def convert_files(self, rmv_src=False):
doStuff()
if rmv_src:
shutil.rmtree(self.__path_to_files)
def doStuff():
# does some stuff
```
Now my tests look like -
```
class TestFileConverter(unittest.TestCase):
def test_convert_success(self):
input_dir = 'resources/files'
file_converter = FileConverter(input_dir)
file_converter.convert_files()
# assert the things from doStuff
@mock.patch('shutil.rmtree')
def test_convert_with_rmv(self, rm_mock):
input_dir = 'resources/files'
file_converter = FileConverter(input_dir)
file_converter.convert_files(True)
self.assertEquals(rm_mock, [call(input_dir)])
```
Now when I run this testsuite the test with rmv gives me assertionError
```
!= [call('resources/images')]
```
and the first test gives me file not found error since the mock did not work and the rmv source test removed the file
```
FileNotFoundError: [Errno 2] No such file or directory: 'resources/images'
```
If I comment out the second test with rmv\_source true then my first test works fine.
What am I doing wrong here?<issue_comment>username_1: Your module has already imported `shutil.rmtree` so mocking it later in the test suite won't do anything.
You need to mock the module when you import `FileConverter`, not afterwards.
```
import sys
from mock import MagicMock
sys.modules['shutil'] = MagicMock()
# and/or
sys.modules['shutil.rmtree'] = MagicMock()
import FileConverter
```
If you still need to use shutil in your test code, then first import it using an alias,and use that when you need the 'real' module:
```
import sys
from mock import MagicMock
import shutil as shutil_orig
sys.modules['shutil'] = MagicMock()
import shutil
print(type(shutil_orig.rmtree))
#
print(type(shutil.rmtree))
#
```

```
@mock.patch('shutil.rmtree')
def test_convert_with_rmv(self, rm_mock):
input_dir = 'resources/files'
rm_mock.return_value = 'REMOVED'
file_converter = FileConverter(input_dir)
file_converter.convert_files(True)
rm_mock.assert_called_with(input_dir)
self.assertEqual(rm_mock.return_value, 'REMOVED')
```
The `test_convert_with_rmv` has no way removed the `input_dir`, it probably never created in the first place. You could assert this statement in each test before and after `convert_files` called:
```
self.asserTrue(os.path.isdir(input_dir))
```

I created a multiple table tag to with Power description but I cant align the level2 and level3 table tag from Level1. Another query. How can I create another sets of Level's that will be under to no Power? but I'm not able to get the desired result.
actually the required is to create 8 sets of Level horizontally. The description name is fixed for individual boxes from L1-Sample1 to L3-Good.
Please see below my initial HTML code.
```html

> ***[Take reference for table here](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/table)***

Also when you write markup, its better to validate your code...you can use **[html validator](https://validator.w3.org/#validate_by_input)** to validate it
You will need to wrap your tables inside a main table to align them like below
```css
table {
border-collapse: collapse;
font: 13px Verdana;
}
h3 {
margin: 0;
}
table,
tr,
td {
border: 1px solid #000;
}
table table td {
padding: 10px;
}
td {
vertical-align: top;
}
```

2018/03/20 | 984 | 4,037 | <issue_start>username_0: I am trying to retrieve a row from database , changing certain columns value in it and adding it as new row (Entity Framework Core),
But it is giving me error
>
> Cannot insert explicit value for identity column in table 'Audit\_Schedules' when IDENTITY\_INSERT is set to OFF.
>
>
>
This table have a Primary Key **"ScheduleId"**
Below is my Code
```
AuditSchedules _schedules = new AuditSchedules();
using (var ctx = new QuestionnaireEntities(_configuration))
{
_schedules = ctx.AuditSchedules.Where(x => x.ScheduleId == model.ScheduleID).SingleOrDefault();
_schedules.StaffId = model.TransferedAuditorCode;
_schedules.StaffName = model.TransferedAuditorName;
_schedules.FromDate = _schedules.ToDate = Convert.ToDateTime(model.TransferedScheduleDate);
ctx.AuditSchedules.Add(_schedules);
ctx.SaveChanges();
_subschedules = ctx.AuditSubSchedule.Where(x => x.SubScheduleId == model.SubScheduleID).SingleOrDefault();
_subschedules.IsHoliDay = "Y";
_subschedules.HolidayType = model.HolidayType;
_subschedules.TransferedScheduleId = _schedules.ScheduleId.ToString();
ctx.AuditSubSchedule.Update(_subschedules);
ctx.SaveChanges();
}
```
Error Comes In
```
ctx.AuditSchedules.Add(_schedules);
```
First I thought its conflicting in value of Schedule\_ID and not able to add duplicate Primary Key , But Schedule\_ID is auto generated field so this issue should not occur
I also tried setting it to different value
```
_schedules.ScheduleId = 0;
```
but it does not insert .
How Can I replicate a row with few changes in it (want to add a new row but modified values)<issue_comment>username_1: The error is simple, it is because you are adding the identity insert as a part of insert. If it is identity, it has to be auto generated. So either turn off before insert and then turn it on. Or make it auto generated.
This error will be the same if you try and insert the same data from sql server.
This is basically propagated from sql server.
If you do not want an ID to be database generated, then you should use the DatabaseGenerated attribute on your model, as in
```
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public int ScheduleId {get;set;}
```
If you want the identity insert to be off you can try the technique [here](https://stackoverflow.com/questions/40896047/how-to-turn-on-identity-insert-in-net-core)
Upvotes: 0 <issue_comment>username_2: EF Core behavior with auto generated values on insert is different than EF6.
First, the property must have default value (`0`) in order to be auto generated. This allows identity inserts which was not possible in EF6.
Second, the entity being added should not be already tracked by the context, because otherwise the context keeps internally some information that the entity key has been set and will include the value (even `0`) in the generated `INSERT` command, which in turn causes the exception you are getting.
To achieve the goal, *before* calling the `Add` method:
First make sure the entity is not tracked by either using [No-tracking query](https://learn.microsoft.com/en-us/ef/core/querying/tracking#no-tracking-queries) when obtaining it
```
_schedules = ctx.AuditSchedules
.AsNoTracking() // <--
.Where(x => x.ScheduleId == model.ScheduleID)
.SingleOrDefault();
```
or explicitly detaching it
```
ctx.Entry(_schedules).State = EntityState.Detached;
```
Then reset the PK
```
_schedules.ScheduleId = 0;
```
The do other modifications and finally call
```
ctx.AuditSchedules.Add(_schedules);
```
This will work for simple entities w/o navigation properties / FKs. For complex entity graph you should use no tracking query, and then work with it the same way as with detached entity graphs.

2018/03/20 | 1,793 | 7,363 | <issue_start>username_0: I have an ASP.NET Core 2.0 app hosted on an Azure App Service.
This application is bound to `domainA.com`. I have one route in my app—for example, `domainA.com/route`.
Now, I want to introduce another domain, but have it respond only to a different route—for example, `domainB.com`.
What is the best way to do this?<issue_comment>username_1: One way to accomplish this is to make a [custom route constraint](https://www.c-sharpcorner.com/article/creating-custom-routing-constraint/) to specify which routes function for each domain name.
DomainConstraint
----------------
```
public class DomainConstraint : IRouteConstraint
{
private readonly string[] domains;
public DomainConstraint(params string[] domains)
{
this.domains = domains ?? throw new ArgumentNullException(nameof(domains));
}
public bool Match(HttpContext httpContext, IRouter route, string routeKey, RouteValueDictionary values, RouteDirection routeDirection)
{
string domain =
#if DEBUG
// A domain specified as a query parameter takes precedence
// over the hostname (in debug compile only).
// This allows for testing without configuring IIS with a
// static IP or editing the local hosts file.
httpContext.Request.Query["domain"];
#else
null;
#endif
if (string.IsNullOrEmpty(domain))
domain = httpContext.Request.Host.Host;
return domains.Contains(domain);
}
}
```
Usage
-----
```
app.UseMvc(routes =>
{
routes.MapRoute(
name: "DomainA",
template: "route",
defaults: new { controller = "DomainA", action = "Route" },
constraints: new { _ = new DomainConstraint("domaina.com") });
routes.MapRoute(
name: "DomainB",
template: "route",
defaults: new { controller = "DomainB", action = "Route" },
constraints: new { _ = new DomainConstraint("domainb.com") });
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
```
Note that if you fire this up in Visual Studio it won't work with the standard configuration. To allow for easy debugging without changing the configuration, you can specify the URL with the domain as a query string parameter:
```
/route?domain=domaina.com
```
This is just so you don't have to reconfigure IIS and your local hosts file to debug (although you still can if you prefer that way). During a `Release` build this feature is removed so it will only work with the *actual* domain name in production.
Since routes respond to *all domain names* by default, it only makes sense to do it this way if you have a large amount of functionality that is shared between domains. If not, it is better to setup separate areas for each domain:
```
routes.MapRoute(
name: "DomainA",
template: "{controller=Home}/{action=Index}/{id?}",
defaults: new { area = "DomainA" },
constraints: new { _ = new DomainConstraint("domaina.com") }
);
routes.MapRoute(
name: "DomainA",
template: "{controller=Home}/{action=Index}/{id?}",
defaults: new { area = "DomainB" },
constraints: new { _ = new DomainConstraint("domainb.com") }
);
```

=> IRouteConstraint.cs
```
using System;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
namespace Microsoft.AspNetCore.Routing
{
public class ConstraintHost : IRouteConstraint
{
public string _value { get; private set; }
public ConstraintHost(string value)
{
_value = value;
}
public bool Match(HttpContext httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
string hostURL = httpContext.Request.Host.ToString();
if (hostURL == _value)
{
return true;
}
//}
return false;
//return hostURL.IndexOf(_value, StringComparison.OrdinalIgnoreCase) >= 0;
}
public bool Match(HttpContext httpContext, IRouter route, string routeKey, RouteValueDictionary values, RouteDirection routeDirection)
{
throw new NotImplementedException();
}
}
public class ConstraintHostRouteAttribute : RouteAttribute
{
public ConstraintHostRouteAttribute(string template, string sitePermitted)
: base(template)
{
SitePermitted = sitePermitted;
}
public RouteValueDictionary Constraints
{
get
{
var constraints = new RouteValueDictionary();
constraints.Add("host", new ConstraintHost(SitePermitted));
return constraints;
}
}
public string SitePermitted
{
get;
private set;
}
}
}
```
And in your Controller can use it like that:
```
[ConstraintHostRoute("myroute1/xxx", "domaina.com")]
[ConstraintHostRoute("myroute2/yyy", "domainb.com")]
public async Task MyController()
{
return View();
}
```

Since ASP.NET Core 3—and with continued support in ASP.NET Core 5 and 6—you can restrict individual route definitions to specific hostnames by using the **[`RequireHost()`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.builder.routingendpointconventionbuilderextensions.requirehost?view=aspnetcore-3.1)** extension method, as discussed in [Allow routing to areas by hostname](https://github.com/dotnet/aspnetcore/issues/8264). (Contrary to the issue title, this isn't specific to areas.)
### Example
So, to adapt [@nightowl888's example in the accepted answer](https://stackoverflow.com/a/49393828/3025856), you can now accomplish the same result without having to define a custom `IRouteConstraint`:
```cs
app.UseMvc(routes =>
{
routes.MapRoute(
name: "DomainA",
template: "route",
defaults: new { controller = "DomainA", action = "Route" }
).RequireHost("domaina.com");
routes.MapRoute(
name: "DomainB",
template: "route",
defaults: new { controller = "DomainB", action = "Route" }
).RequireHost("domainb.com");
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}"
);
});
```
### Attribute Routing
Alternatively, if you prefer attribute routing, [as used in @yanga's approach](https://stackoverflow.com/a/50635119/3025856), you can now use the new (but poorly documented) **[`HostAttribute`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.routing.hostattribute?view=aspnetcore-5.0)** ([source code](https://github.com/dotnet/aspnetcore/blob/master/src/Http/Routing/src/HostAttribute.cs)):
```cs
[Host("domainb.com")]
public DomainController: Controller
{
…
}
```
Obviously, this doesn't address the original problem, which was for ASP.NET Core 2. As this is an un(der)documented feature, however, I wanted to leave it here for people trying to solve this problem for ASP.NET Core 3+.

2018/03/20 | 1,043 | 3,841 | <issue_start>username_0: I have multiple buttons 0 to 9 and other calculation methods like plus, minus, etc
There are two display items, `Memory` and `Display`; `Memory` item is hidden.
When click on `1` button then display value 1 in `Display` item. When click on `+` button then store value 1 in `Memory` item. When click on `=` button then add `Memory` + `Display` values and show answer on `Display` item.
Question is how to code multiple calculation in equal to `=` button?<issue_comment>username_1: You have three registers: the button clicked, the display value and the memory value. So the calculation string `2+3=5` looks something like this:
```
button Display Memory
2 2
+ 2 2
3 3 2
= 5 5
```
As I understand your question, you want to handle a longer calculation, when the user types in several steps without pressing `=`, for instance `2+3+7/4*5=`. There are several ways to do this, but the most intuitive one for the user is to treat the arithmetic operators as having an implicit `=` operation, calculating the running sum and displaying that value.
```
button Display Memory
2 2
+ 2 2
3 3 2
+ 5 5
7 7 5
/ 12 12
4 4 12
* 3 3
5 5 3
= 15 15
```
To make this work you need another register item to track the current operator.
```
button Display Memory Operator
2 2
+ 2 2 +
3 3 2 +
+ 5 5 +
7 7 5 +
/ 12 12 /
4 4 12 /
* 3 3 *
5 5 3 *
= 15 15 =
```
So when the user clicks a triggering button you execute something like this:
```
if :operator = '+' then
:memory := :memory + :display;
elsif :operator = '-' then
:memory := :memory - :display;
elsif :operator = '/' then
:memory := :memory / :display;
elsif :operator = '*' then
:memory := :memory * :display;
end if;
:display := :memory;
:operator := :button_value;
```
You will need to decide how to handle the situation when the user types two operations in a row e.g. `+/`. But probably you need to track previous button press too.
So what is the purpose of `=`? Well, it depends on what the user types next. If they follow `=` with another operator then it's just a subtotal and the sum continues....
```
button Display Memory
2 2
+ 2 2
3 3 2
= 5 5
+ 2 5 <-- continue with existing sum
= 7 7
```
... but if they follow it with a number then we're starting a new sum and we reset the memory:
```
button Display Memory
2 2
+ 2 2
3 3 2
= 5 5
2 2 <-- start a new sum
+ 2 2
2 2 2
= 4 4

Below is the scenario i have, and the data model is tightly coupled classes.
```
public interface BaseEntity extends Serializable, Cloneable, Observable
{
public void setId(long id);
public long getId();
... few other generic attributes
}
public class BaseClass implements BaseEntity {
protected long id;
public void setId(long id)
{
this.id = id;
}
public long getId()
{
return objectId;
}
.. few other attributes
}
public class AuditableBaseClass extends BaseClass implements BaseEntity, Audit
{
... few other attributes
}
public class Car extends AuditableBaseClass {
.... some attributes
}
public class Bike extends AuditableBaseClass {
...some attributes
}
public class Truck extends AuditableBaseClass {
... some attributes
}
```
If we look at the existing .hbm.xml file below, Used different sequence for the different classes
```
SEQ\_CAR
<
// some other properties
SEQ\_BIKE
// some other properties
SEQ\_TRUCK
```
Simple definition for @Id using sequence is as below
```
@Id
@GeneratedValue( strategy = GenerationType.SEQUENCE, generator = "sequence-generator" )
@SequenceGenerator( name = "sequence-generator", sequenceName = "SEQ_NAME" )
```
For a fact that i know we need to use `@MappedSuperclass` to represent the super class. How to represent **sequence attribute for an @Id** column which is using **a different sequence for different child classes though all classes inherit the attribute id but uses different sequences for each.**
Any help on this please?<issue_comment>username_1: Hibernate 5.2 doesn't allow us to have two identifier generators with the same name even they have different configurations because the scope is global as stated in JPA Spec. Because of that, you need to define your identifiers and generators in the entity classes.

After that use @SequenceGenerator in child class and set name attribute with generator in BaseClass.
```
@MappedSuperclass
public class BaseClass implements BaseEntity {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "my_seq_gen")
@Column(name = "ID")
protected long id;
public void setId(long id)
{
this.id = id;
}
public long getId()
{
return objectId;
}
.. few other attributes
}
public class AuditableBaseClass extends BaseClass implements BaseEntity, Audit
{
... few other attributes
}
@Entity
@Table(name="car")
@SequenceGenerator(sequenceName = "car_id_seq", allocationSize = 1, name = "my_seq_gen")
public class Car extends AuditableBaseClass {
.... some attributes
}
@Entity
@Table(name="bike")
@SequenceGenerator(sequenceName = "bike_id_seq", allocationSize = 1, name = "my_seq_gen")
public class Bike extends AuditableBaseClass {
.... some attributes
}
@Entity
@Table(name="truck")
@SequenceGenerator(sequenceName = "truck_id_seq", allocationSize = 1, name = "my_seq_gen")
public class Truck extends AuditableBaseClass {
... some attributes
}

'27-SEP-97' i.e DD-MON-YY
Now I want to convert this to YYYYMMDD. I am using the following script to convert this.
```
TO_CHAR(TO_DATE(CHD_DATE_FIRST_ACT,'DD-MON-YY'),'YYYYMMDD')
```
but this is giving me the following output.
```
20970927
```
I want this data to be in YYYYMMDD format, such that the output looks like this- **19970927**<issue_comment>username_1: If '27-SEP-97' is a string (which is what your words suggest), then such a combination of TO\_this and TO\_that might do the job:
```
SQL> with test as (select '27-SEP-97' datum from dual)
2 select to_char(to_date(datum, 'dd-mon-rr', 'nls_date_language = english'), 'yyyymmdd') result
3 from test;

`replace` takes 3 arguments as show below
`replace(string,find_string,replace_with)`
you should simply replace `-` with a blank string
if your str is '27-SEP-97' to get the output as `19970927` execute the following in mysql
`select replace(str_to_date('27-SEP-97','%d-%b-%Y'),'-','') as date;`

I encountered an error:
...
from flask\_openid import OpenID
ModuleNotFoundError: No module named 'flask\_openid'
Flask-OpenID is available in my Python v3.5 dist-packages.
(When I run:
"sudo pip3 install Flask-OpenID", it shows
"Requirement already satisfied (use --upgrade to upgrade): Flask-OpenID in /usr/local/lib/python3.5/dist-packages" )
What should I do to install openid for Python 3.6?<issue_comment>username_1: The [documentation](https://pythonhosted.org/Flask-OpenID/#how-to-use) states that you should import `OpenID` as follows:
```
from flask.ext.openid import OpenID
```
The package itself is installed correctly (in your Python3.5 environment), as shown by `pip` when you try to install it again:
>
> Requirement already satisfied (use --upgrade to upgrade): Flask-OpenID in /usr/local/lib/python3.5/dist-packages
>
>
>
However, as you state the in your question:
>
> I was trying to run a Flask project using **Python 3.6**
>
>
>
You might want to make sure your `python3` and `pip3` are actually pointing to where you want them to, e.g. on your terminal:
```
$ ls -l $(which pip3)
```
Or even better, you should really look into creating [virtualenvs](https://virtualenv.pypa.io/en/stable/) for your projects, it helps a lot avoiding these kinds of problems in the first place:
* create a new Python 3.6 virtualenv
* activate your new virtualenv
* install your requirements with pip inside the virtualenv
Then run your script in this virtualenv, and you'll be sure you are using exactly the Python you want, and your dependencies are where you expect them to be (and only there, not somewhere else messing up other projects).
Now this might look like a lot of effort, but it takes no more than a couple minutes the first time you do it, will quickly become second nature, and save you a ton of headache down the road.

```
python3.6 -m pip install flask_openid
```
solved the issue.
The above command will install openid for python3.6.

Example: Sheet 1 Column B, E:J filled with lookup formula to get data from Sheet 2. Formula is filled from row 1 to 1500. Based on table array in sheet 2. Sheet 1 row 1 to 1000 return lookup result. I need to convert column B, E:J row 1 to 1000 formula to value while row 1001 to 1500 is still have lookup formula
From internet search i can use this code...
```
Sub FormulaToValue()
Dim N As Long, rng As Range
N = Cells(Rows.Count, "A").End(xlUp).Row
Set rng = Range(Cells(1, 1), Cells(N, Columns.Count))
rng.Value2 = rng.Value2
End Sub
```
This code will convert formula to value until last row with data only, in this case only row 1 to 1000 will be converted. But this code convert all columns in the sheet. I think i need to change Columns.Count to specific column range but i don't now how to write the right code. I'm not familiar with vba code
Please help. Thank you<issue_comment>username_1: Put the column you require in this line
```
Set rng = Range(Cells(1, 1), Cells(N, Columns.Count))
```
e.g.
If you want to use column E
```
Set rng = Range(Cells(1, 5), Cells(N, 5))
```
If you want to use multiple columns you can use a loop to go through them
```
Sub FormulaToValue()
Dim N As Long, rng As Range
Dim arr As Variant
arr = Array("B", "E", "F", "G", "H", "I", "J")
' Read through each column
Dim col As Variant
For Each col In arr
N = Cells(Rows.Count, col).End(xlUp).Row
Set rng = Range(Cells(1, col), Cells(N, col))
rng.Value2 = rng.Value2
Next col
End Sub
```
If you have columns like B:E then you need to go through them individually to find the last cell with data in each.

The routing is working fine on localhost when refresh,but not working on live. I saw some answers in stackoverflow for IIS in web.config file. But I don't have web.config file under my project structure. can I add it manually or how can I fix it.

eg:-

I fixed it by creating a folder called: users
and inside a file: index.html
```
redirect users
window.location.href = 'http://my-server:4200/';
```
other solutions that i have read:
1) make your server redirect to index.html on a 404 error.
2) make your apache or iis add /index.html at the end of every route path

2018/03/20 | 476 | 1,728 | <issue_start>username_0: I'm trying to save the application's root state on `mounted` lifecycle of VueJS and freeze the copy in `$root`'s `data`, and my attempt is as following,
```
mounted() {
this.globalState = this.$store.state;
},
data () {
return {
globalState: null
}
}
```
However this approach is updating `globalState` so I came up with another way to freeze it by using `Object.freeze()` but with no luck it keeps updating.
Also I've tried to copy the `this.$store.state` to a `const` variable and update `globalState` via it, but it also fails.
My last attempt is as following, I know it's an ugly code but please bear with it.
```
let emptyObj = {};
Object.defineProperty(emptyObj, 'globalState',{
value: this.$store.state,
enumerable: false,
configurable: false,
writable: false
}
);
this.globalState = emptyObj.globalState;

2018/03/20 | 1,039 | 3,749 | <issue_start>username_0: I created a modal which displays information specific to their id entries and placed the Approve and Reject button as below.
[Screenshot of modal](https://i.stack.imgur.com/sYfbM.jpg)
When a user click on "Accept" or "Reject", it needs to pass id related to the viewed entries so the user can perform the requested action, whether to accept or reject the entries (default status is 'pending').
**vendor.blade.php**
```html
@method('PUT')

Approve
@method('PUT')
@csrf
Reject
```
In **VendorController.php**
```
public function index()
{
$vendors = DB::select('select company_name, roc_no, created_at from mides_vendors');
$vendor_id = Vendor::where('status', 'Pending');
return view('panel.vendor', ['vendors' => $vendors]);
}
```
**ApprovedVendorController.php**
```html
php
namespace App\Http\Controllers;
use App\User;
use App\Vendor;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class ApproveVendorController extends Controller
{
public function approve(Request $request, $id)
{
DB::insert('insert into mides_users(name, email, password) select name,roc_no,password from mides_vendors where id = :id', ['id' = $id]);
DB::update('update mides_vendors set status = :status where id = :id', ['status' => 'Approved', 'id' => $id]);
return redirect('/');
}
public function reject(Request $request, $id)
{
DB::update('update mides_vendors set status = :status where id = :id', ['status' => 'Rejected', 'id' => $id]);
return redirect('/');
}
}
```
**routes/web.php**
```html
Route::prefix('/panel')->group(function () {
Route::get('/dashboard', function () {
return view('panel.dashboard');
});
/* These routes only display the information/modal
Route::get('/approve-vendor', 'VendorController@showNewRegistration'); // return vendor.blade.php
Route::get('/vendor-approved', 'VendorController@showApproved'); // return vendor-approve.blade.php
Route::get('/vendor-reject', 'VendorController@showRejected'); // return vendor-reject.blade.php
/* These route used to perform the specific action */
Route::put('/approve/{id}', 'ApproveVendorController@approve')->name('approve');
Route::put('/reject{id}', 'ApproveVendorController@reject')->name('reject');
});
```
However, it returns this error.
[Error got after clicking Accept or Reject](https://i.stack.imgur.com/248Mr.jpg)
How do I pass the id of data? I tried as shown in [pass the database value to modal popup](https://stackoverflow.com/questions/39827189/pass-the-database-value-to-modal-popup) to create the modal using second answer option (besides the ajax ones). Do I need to create another controller for these?
Edited: after do as explained by @Wreigh, it works, means that the status changed from 'pending' to 'accept/reject'. But, when I return to the previous page, which is the `/panel/approve-vendor` (the page is used for showing the pending list modal) then I got the error `undefined variable vendorId`.<issue_comment>username_1: I had almost the same problem.

```
import React from "react";
import { toast } from 'react-toastify';
class MyView extends React.Component<{}, {}> {
constructor() {
super();
this.state = {
};
}
componentDidMount() {
toast("Hello", { autoClose: false });
}
notify = () => toast("Hello", { autoClose: false });
render() {
return (
Notify
)}
}
```
package.json (in "dependencies" section)
```
"react": "^16.2.0",
"react-toastify": "^3.2.2"
```
If I debug it, I see that my toasts are queued, \_EventManager2 never gets the \_constant.ACTION.MOUNTED event that normally emits the toasts from the queue...
```
/**
* Wait until the ToastContainer is mounted to dispatch the toast
* and attach isActive method
*/
_EventManager2.default.on(_constant.ACTION.MOUNTED, function (containerInstance) {
container = containerInstance;
toaster.isActive = function (id) {
return container.isToastActive(id);
};
queue.forEach(function (item) {
_EventManager2.default.emit(item.action, item.content, item.options);
});
queue = [];
});
```
..so there might be something wrong with that ToastContainer but what? I just use the sample code from the documentation.
Thank you for your help!<issue_comment>username_1: You have to also `import 'react-toastify/dist/ReactToastify.css';`
```
import React, { Component } from 'react';
import { ToastContainer, toast } from 'react-toastify';

```
getSomethingFromApi()
.then((response) => {
// this works fine because response.message is a string
toast.notify(response.message)
})
.catch((error) => {
// this will fail to render because error is an object, not a string
toast.error(error)
})

Try to change this:
```
import toast from 'react-toastify';
```
To:
```
import { toast } from 'react-toastify';
```
Also according to all other 'react-toastify' stackoverflow responses, installing latest version causes problem. So try uninstalling it and install older version that your course instructor did or version 4.1 seems to be working for most people.
Uninstall first:
```
npm uninstall react-toastify --save
```
Then install 4.1 version:
```
npm i [email protected]
```

Then:

and after that when you do `toast('hy')`
then it will show toast

2018/03/20 | 858 | 3,742 | <issue_start>username_0: * I am using "TextWebSocketHandler" for websockets and "WebSocketConfigurer" to configure the websocket.
* I have a scenario where different instances of the handler needs to be gererated.
**For example:** if I am doing auction for some items, then I need to generate seperate WebSocketHandler instances for each auctionId.
Could we attach "auctionId" as path parameter to the url so that different instance gets generated for different auction?
Or Is there any other way to achieve this?
This is how I am adding the handler:
```
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(websocketTestHandler(), "/websocket-test");
}
```<issue_comment>username_1: If you want to use a `TextWebSocketHandler`, you could pass the auction id as part of the URL path. You'll have to copy the path to the WebSocket session during handshake (this is the only place where you'll get access to the `ServerHttpRequest` as the handshake is an http request) and then retrieve the attribute from your handler.
Here's the implementation:
```
@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(auctionHandler(), "/auction/*")
.addInterceptors(auctionInterceptor());
}
@Bean
public HandshakeInterceptor auctionInterceptor() {
return new HandshakeInterceptor() {
public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response,
WebSocketHandler wsHandler, Map attributes) throws Exception {
// Get the URI segment corresponding to the auction id during handshake
String path = request.getURI().getPath();
String auctionId = path.substring(path.lastIndexOf('/') + 1);
// This will be added to the websocket session
attributes.put("auctionId", auctionId);
return true;
}
public void afterHandshake(ServerHttpRequest request, ServerHttpResponse response,
WebSocketHandler wsHandler, Exception exception) {
// Nothing to do after handshake
}
};
}
@Bean
public WebSocketHandler auctionHandler() {
return new TextWebSocketHandler() {
public void handleTextMessage(WebSocketSession session, TextMessage message) throws IOException {
// Retrieve the auction id from the websocket session (copied during the handshake)
String auctionId = (String) session.getAttributes().get("auctionId");
// Your business logic...
}
};
}
}
```
**Client:**
```
new WebSocket('ws://localhost:8080/auction/1');
```
Even if this is a working solution, I would recommend you taking a look at [STOMP over WebSockets](https://docs.spring.io/spring/docs/current/spring-framework-reference/web.html#websocket-stomp), it will give you more flexibility.
Upvotes: 5 [selected_answer]<issue_comment>username_2: Another option would be to get the value from the session URI.
See example below where I check if the session contains the Box value.
URI is like /chat/{box}
```
@Override
public void handleTextMessage(WebSocketSession session, TextMessage message)
throws IOException {
Map value = new Gson().fromJson(message.getPayload(), Map.class);
String sender = value.get("sender");
String content = value.get("content");
String box = value.get("box");
for (WebSocketSession webSocketSession : sessions) {
LOGGER.info("Get messages on box {} and URI {}", box, session.getUri().toString());
if (webSocketSession.getUri().toString().contains(box)) {
webSocketSession.sendMessage(new TextMessage(sender + ": " + content + " !"));
}
}
}
```
In that case you don't need an interceptor.

2018/03/20 | 743 | 2,740 | <issue_start>username_0: I have just opened an old project here at work. Someone appears to have changed the indentation. It's set to 2 spaces instead of four space tabbing.
[](https://i.stack.imgur.com/NYv7w.png)
What I have tried:
1. I tried doing a `Ctrl` + `K``D` but that hasn't changed it back to proper indentation.
2. I Deleted the `_ReSharper.Caches` directory, and a new one is just created, no change to the indentation.
When those didn't work, I have started comparing settings in my visual studio with two different solutions.
Resharper settings appear to be identical so are the settings in visual studio.
**Re-sharper settings**
[](https://i.stack.imgur.com/2Zfx7.png)
**Visual studio settings**
[](https://i.stack.imgur.com/cxSn9.png)
Which makes me think this must be in one of the project files or something? If it's not an issue with the settings in my visual studio, what's overriding the tabbing?
Of note when the project loads I swear it loads with proper indentation and then it's reformatted in the last second. Not sure it matters, but the projects are .net core 1.0 there are three projects in the solution all three appear to be affected.
Hope someone has a fix for this; it's really hard to read it like this.<issue_comment>username_1: Visual Studio may be using an [.editorconfig](https://learn.microsoft.com/en-us/visualstudio/ide/create-portable-custom-editor-options) file in the project's directory (or in any parent directory) which allows for a consistent code style within a codebase regardless of user settings.
Visual Studio should indicate this in the lower left-hand area of the IDE window.
If this is the case, you'll need to modify `.editorconfig` and define a new style in order to change the configuration for the automatic formatting tools.
Upvotes: 6 [selected_answer]<issue_comment>username_2: As people says in answers and comments this is probably a `.editorconfig`. In our case a developer started using VS Code and when upgrading to VS 2017 Visual Studio also accepts these files.
This was the value in the file that was automatically added:
```
[*]
end_of_line = crlf
insert_final_newline = true
indent_style = space
indent_size = 2
trim_trailing_whitespace = true
```
By adding this we could use C# normally and the developer who wanted to use VS Code could continue to do that:
```
[*.cs]
indent_style = space
indent_size = 4
```

I put these 40-50 statements in try , catch block and able to parse but issue is one exception is generated other statement will not be extracted so I started putting each comment inside a try catch block .
```
try{
statment: 1
statment:2
.
.
.statement 30
}
```
how to handle elegantly such scenario in scala to capture exception in each statement and continue building map structure without puting each statement inside separate try catch block.
```
try{
stat1
}
try{
stat2
}
....
```
Actual Code:-
```
var mp = scala.collection.immutable.Map[String, Any]()
try{
// working on json payload
var jsonpayloadstr= cleanstr.split("\"\\{\"")(1).split(",\"\\[")(0).split("\\}\",")(0).toString
jsonpayloadstr ="{\""+jsonpayloadstr +"}"
var jobj=scala.util.parsing.json.JSON.parseFull(jsonpayloadstr)
var bdmap=jobj.get.asInstanceOf[Map[String, Map[String, Any]]]("Boundary")
bdmap.map(x=>mp=mp+(x._1->x._2))
//batterystatus
var batterystatus= jobj.get.asInstanceOf[Map[String, Map[String, Map[String,Double]]]]("Notification")("Data")("BatteryStatus")
mp=mp+("BatteryStatus"->batterystatus.toInt)

mp=mp+("TagID"-> tagId)
//brechID

}
catch{
case e: Exception => {
println("Oops none get 123455dsdsd677")
}
}
```
Thanks<issue_comment>username_1: If you want to keep on parsing the other variables even if one fails, you can do something like:
```
val batterystatus = Try(...).toOption
val locationMap = Try(...).toOption
...
```
That way you'll have values for everything that parsed correctly and you'll be forced to think about how to handle the ones that didn't.

We shouldn't use exception-based extractions. Put your regexes in a list and map the list with the according extraction function, something like regex => Option[element] and flatten the list after.

2018/03/20 | 1,457 | 5,835 | <issue_start>username_0: I've discovered a weird behavior on iOS 11 when I push `UIViewController` and change the `UINavigationBar` color to transparent. Important thing is that I'm using `largeTitles`.
1. I want to change red color of the navigation bar to transparent and this works fine.
2. However, if I tap on backButton, disable transparent style and red color style again something bad happened. NavigationBar on the ViewController is not red but still transparent.
3. As @Menoor Ranpura suggest I add another line which sets also a `backgroundColor` of view in `UIViewController` - and this is fine workaround when you set the same color like on `UINavigationBar`. However, it's not the solution for the problem because the large part of the navigation bar is still transparent. You can see it when you set the different color for a background. For example, I set the yellow. You can see the example here:
[](https://i.stack.imgur.com/UenjC.gif)
Question
========
How to properly change the navigation bar color **from transparent** to **red again**, when the `prefersLargeTitles` is set to `true`?
Code
====
```
class ExampleTableTableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "reuseID")
navigationController?.navigationBar.redNavigationBar()
title = "Red NavBar"
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
view.backgroundColor = .yellow
navigationController?.navigationBar.redNavigationBar()
}
}
//Transparent Navigation bar controller
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
title = "Transparent NavBar"
view.backgroundColor = .blue
self.navigationController?.navigationBar.prefersLargeTitles = true
}
override func viewWillAppear(_ animated: Bool) {
self.navigationController?.navigationBar.transparentNavigationBar()
}
}
extension UINavigationBar {
func redNavigationBar() {
setBackgroundImage(nil, for: .default)
shadowImage = nil
prefersLargeTitles = true
tintColor = .white
largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
barTintColor = .red
}
func transparentNavigationBar() {
setBackgroundImage(UIImage(), for: .default)
shadowImage = UIImage()
}
}
```
Some tips that I've already tested:
-----------------------------------
* Everything works fine when `prefersLargeTitles` is set to `false`
* Everything works fine when `prefersLargeTitles` is set to `true`, but `navigationBar` changes are between non transparent colors. For example, if changing between green <-> yellow
* I don't want to set `backgroundColor` on view. It's not an solution but kind of a workaround for this.
Here you can see a screen from XCode:
[](https://i.stack.imgur.com/4lInn.png)
Interesting fact is that, there is something called: `_UINavigationBarLargeTitleView` which is transparent. **How to access it?**

---
UPDATE referring to @Menoor Ranpura answer
==========================================
Code that @Menoor Ranpura suggest is a kind of a workaround. It's not a solution to set the same `backgroundColor` on `UIViewController` view like `UINavigationBar` has. However, I go a bit further and I change the color for a different than `UINavigationBar` controller has. And as you can see on above gif, when the `largeTitle` appears, the navigation bar becomes yellow - which means that is transparent - because we're able to see the yellow background of view.<issue_comment>username_1: call **greenNavigationBar()** in **viewWillAppear**
```
override func viewWillAppear(_ animated: Bool)
{
view.backgroundColor = .red // this is kind of a workaround, However if you set color which will be different that `UINavigationBar` color you see that `largeTitle` is transparent because it shows a `backgroundColor` of a ViewController view.
navigationController?.navigationBar.greenNavigationBar()
title = "Green Title"
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Next", style: .plain, target: self, action: #selector(showTransparentViewController))

```
val mySnackbar = Snackbar.make(findViewById(R.id.container),"Item added to cart.", Snackbar.LENGTH_SHORT)
mySnackbar.setAction("view cart", View.OnClickListener {/*action to be triggered*/ })
mySnackbar.setActionTextColor(/*color defined*/)
mySnackbar.show()
```
I implemented this in Kotlin.
Upvotes: 0 <issue_comment>username_2: With the Material Components Library you can do it.
Just add the **`snackbarButtonStyle`** attribute in your theme app.
```
<!-- Style to use for action button within a Snackbar in this theme. -->
<item name="snackbarButtonStyle">@style/snackbar\_button</item>
...
```
Then define your custom style:
```
<item name="backgroundTint">@color/secondaryLightColor</item>
<item name="android:textColor">@color/primaryDarkColor</item>
```

I was wondering, what could be a possible cause for this? Is this likely a `build.sbt` misconfiguration issue? Common coding style pitfall?<issue_comment>username_1: In my experience this is most often caused by incremental compiler not recompiling enough of your sources on certain changes. One particular issue I have seen is method signature changes where only the inferred return type changed to cause this, like when changing:
```
def x(a: Int, b: Double) = a
```
to
```
def x(a: Int, b: Double) = b
```
If this is the case, using explicit return types often helps:
```
def x(a: Int, b: Double): Double = a
```
(In reality more complex code is required to trigger the issue.)
To me this happens both in Scala JS and Scala JVM. In Scala JVM it most often shows not during linking, but during execution, with the exception `NoSuchMethodError` thrown.

2018/03/20 | 867 | 2,343 | <issue_start>username_0: i have a set of arrays:
```
$nums = array(2,3,1);
$data = array(11,22,33,44,55,66);
```
what i want to do is to get a set of $data array from each number of `$nums` array,
the output must be:
```
output:
2=11,22
3=33,44,55
1=66
```
what i tried so far is to slice the array and remove the sliced values from an array but i didn't get the correct output.
```
for ($i=0; $i < count($nums); $i++) {
$a = array_slice($data,0,$nums[$i]);
for ($x=0; $x < $nums[$i]; $x++) {
unset($data[0]);
}
}
```<issue_comment>username_1: Another alternative is to use another flavor [`array_splice`](http://php.net/manual/en/function.array-splice.php), it basically takes the array based on the offset that you inputted. It already takes care of the unsetting part since it already removes the portion that you selected.
```
$out = array();
foreach ($nums as $n) {
$remove = array_splice($data, 0, $n);
$out[] = $remove;
echo $n . '=' . implode(',', $remove), "\n";
}
// since nums has 2, 3, 1, what it does is, each iteration, take 2, take 3, take 1
```
[Sample Output](https://3v4l.org/uUQVm)
Also you could do an alternative and have no function usage at all. You'd need another loop though, just save / record the last index so that you know where to start the next num extraction:
```
$last = 0; // recorder
$cnt = count($data);
for ($i = 0; $i < count($nums); $i++) {
$n = $nums[$i];
echo $n . '=';
for ($h = 0; $h < $n; $h++) {
echo $data[$last] . ', ';
$last++;
}
echo "\n";
}
```

```
$nums = array(2,3,1);
$data = array(11,22,33,44,55,66);
foreach( $nums as $num ){
$t = array();
for ( $x = $num; $x>0; $x-- ) $t[] = array_shift($data);
echo $num . " = " . implode(",",$t) . "
";
}
```
This will result to:
```
2 = 11,22
3 = 33,44,55
1 = 66
```

You can store many values in a table and put that single table in a variable, or into another table if you want many tables stored in one place.

2018/03/20 | 1,169 | 3,426 | <issue_start>username_0: Recently, I have studied 'Programming language' using standard [ML](http://en.wikipedia.org/wiki/ML_%28programming_language%29), and I've learned currying method(or something), so I applied it in Python.
The below is simple function and currying.
```
def range_new(x, y):
return [i for i in range(x, y+1)]
def curry_2(f):
return lambda x: lambda y: f(x, y)
def uncurry_2(f):
pass # I don't know it...
print(range_new(1, 10))
curried_range = curry_2(range_new)
countup = curried_range(1)
print(countup(10))
print(curried_range(1)(10))
```
The result is below. And it works well; with `curry_2` we can make a new function(`countup`). But, then I want to make an uncurried function.
However, I don't know how I can make it.
How can I do it?
```
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
```<issue_comment>username_1: The easiest solution is to wrap the curried function again with code that uncurries it:
```
def uncurry_2(f):
return lambda x, y: f(x)(y)
uncurried_range = uncurry_2(curried_range)
print(uncurried_range(1, 10))
```
Upvotes: 5 [selected_answer]<issue_comment>username_2: It's not exactly good style but you can access the variables in the closure using the (maybe CPython-only) [`__closure__`](https://docs.python.org/reference/datamodel.html#index-34) attribute of the returned `lambda`:
```
>>> countup.__closure__[0].cell_contents
```
This accesses the content of the innermost closure (the variable used in the innermost `lambda`) of your function `curry_2` and thus returns the function you used there.
However in production code you shouldn't use that. It would be better to create a class (or function) for currying that supports accessing the uncurried function (which is something `lambda` does not provide). However some functools in Python support accessing the "decorated" function, for example `partial`:
```
>>> from functools import partial
>>> countup = partial(range_new, 1)
>>> print(countup(10))
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> countup.func
```
Upvotes: 3 <issue_comment>username_3: I believe by uncurry you mean you'd like to allow the function to accept more arguments. Have you considered using the "partial" function? It allows you to use as many arguments as desired when calling the method.
```
from functools import partial
def f(a, b, c, d):
print(a, b, c, d)
g = partial(partial(f, 1, 2), 3)
g(4)
```
Implementing it should be pretty straight forward
```
def partial(fn, *args):
def new_func(*args2):
newArgs = args + args2
fn(*newArgs)
return new_func;
```
Note both the code presented in the original question, and the code above is known as partial application. Currying is more flexible than this typically - here's how you can do it with Python 3 (it is more tricky in Python 2).
```
def curry(fn, *args1):
current_args = args1
sig = signature(fn)
def new_fn(*args2):
nonlocal current_args
current_args += args2
if len(sig.parameters) > len(current_args):
return new_fn
else:
return fn(*current_args)
return new_fn
j = curry(f)
j(1)(2, 3)(4)
```
Now back to your code. range\_new can now be used in a few new ways:
```
print(range_new(1, 10))
curried_range = curry(range_new)
countup = curried_range(1)
print(countup(10))
countup_again = curried_range
print(countup_again(1, 10))
```

2018/03/20 | 1,557 | 5,194 | <issue_start>username_0: What is the correct way to declare a date in a swagger-file object? I would think it is:
```
startDate:
type: string
description: Start date
example: "2017-01-01"
format: date
```
But I see a lot of declarations like these:
```
startDate:
type: string
description: Start date
example: "2017-01-01"
format: date
pattern: "YYYY-MM-DD"
minLength: 0
maxLength: 10
```<issue_comment>username_1: The [OpenAPI Specification](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#data-types) says that you must use:
```yaml
type: string
format: date # or date-time
```
The internet date/time standard used by OpenAPI is defined in [RFC 3339, section 5.6](https://www.rfc-editor.org/rfc/rfc3339#section-5.6) (effectively ISO 8601) and examples are provided in section 5.8. So for `date` values should look like "2018-03-20" and for `date-time`, "2018-03-20T09:12:28Z". As such, when using `date` or `date-time`, the `pattern` should be omitted.
If you need to support dates/times formatted in a way that differs to RFC 3339, you are **not** allowed to specify your parameter as `format: date` or `format: date-time`. Instead, you should specify `type: string` with an appropriate `pattern` and remove `format`.
Finally, note that a `pattern` of `"YYYY-MM-DD"` is invalid according to the specification: `pattern` must be a **regular expression**, not a placeholder or format string.
Upvotes: 9 [selected_answer]<issue_comment>username_2: *pattern* should be a regular expression. This is stated in the [OpenAPI Specification](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.1.md#schema-object).

If a web service exposes a date or a date-time that doesn't conform to the Internet Date/Time Format described in [RFC3339](https://xml2rfc.tools.ietf.org/public/rfc/html/rfc3339.html#anchor14), then *date* and *date-time* are not valid values for the *format* field. The property must be defined as having a *type* equal to *string* without using *format*. Instead, *pattern* can be used to give a regular expression that defines the date or date-time pattern. This allows a client tool to automatically parse the date or date-time.
I also recommend putting the format in the description field so human consumers can read it more easily.

<https://swagger.io/docs/specification/data-models/data-types/>
An optional format modifier serves as a hint at the contents and format of the string. OpenAPI defines the following built-in string formats:
**date** – full-date notation as defined by RFC 3339, section 5.6, for example, 2017-07-21
**date-time** – the date-time notation as defined by RFC 3339, section 5.6, for example, 2017-07-21T17:32:28Z
```
BookingNoteRequest:
type: object
properties:
note:
type: string
postedDate:
type: string
format: date
example: '2022-07-01'
postedTime:
type: string
format: date-time
example: '2017-07-21T17:32:28Z'
```
If the date or date-time format does not follow the standard as defined by RFC 3339, then the *format* field should be removed and the *pattern* field added with a regular expression defining the format.

puts "You have #{gold} gold left over."
@inventory.push([item.name,item.price,item.attack,item.defence])

else

end
end
end
player = Player.new(10,1,2,6)

```
The `inventory.push` line pushes the element to the array while it is inside the method, but when returned outside the method, the `inventory` array is empty. This is confusing because other variables that were changed inside that method in the same way come back as altered.
sample output when printed from inside the buy method:
```
ITEMS IN INV: [["Dagger", 4, 1, 0], ["Mucky Tunic", 2, 0, 2]]
```
output with `player.inventory.inspect` outside of the method:
```
[]
```<issue_comment>username_1: I figured it out 10 seconds after posting this, after messing about with it for an hour.
I needed to add `inventory` to `def initialize`, and then pass an empty array to `player = Player.new(10,1,2,6)` so it became `player = Player.new(10,1,2,6,[])`.
I still don't know why this works.
Upvotes: 0 <issue_comment>username_2: Whenever you call your `inventory` method:
```
def inventory
@inventory = []
end
```
... it assigns a new (empty) array to `@inventory`, thus overwriting any existing items.
The correct way is to either assign `@inventory` in `initialize` and just return it from within the getter:
```
class Player
def initialize(hp, attack, defence, gold)
@hp = hp
@attack = attack
@defence = defence
@gold = gold
@inventory = []
end
def inventory
@inventory
end
# ...
end
```
or to not assign it at all in `initialize` and use the [conditional assignment](http://ruby-doc.org/core-2.5.0/doc/syntax/assignment_rdoc.html#label-Abbreviated+Assignment) operator:
```
class Player
def initialize(hp, attack, defence, gold)
@hp = hp
@attack = attack
@defence = defence
@gold = gold
end
def inventory
@inventory ||= []
end
# ...
end
```
which will assign `[]` to `@inventory` only if it was `nil` or `false` (i.e. the first time you call `inventory`).
A getter that just returns the corresponding instance variable (as in the former example) can also be created via [`attr_reader`](http://ruby-doc.org/core-2.5.0/Module.html#method-i-attr_reader):
```
class Player
attr_reader :inventory
# ...
end

INNER JOIN
(
SELECT A

GROUP BY A
HAVING
COUNT(DISTINCT B) > 0 AND

2018/03/20 | 528 | 2,059 | <issue_start>username_0: In the following code, I am attempting to iterate over `geoMarkers` and create a Marker for each. The line of code here needs some help:
content: `@Html.Partial("~/Views/Search/_MyPartialView.cshtml", Model.ElementAt(' + i + '))`
In this line above, I am attempting to pass the JavaScript variable `i` into a ASP.NET MVC call, which I know by searching isn't possible EXCEPT in cases where the JavaScript variable can be turned into a literal. In this case, I would like to turn the `i` into an int, but I'm struggling with the syntax. **How can I pass `i` into the `@Html.Partial` call?** Note that `_MyPartialView.cshtml` takes a `@model MyMarkerObject`.
Thank you!
```
@model List
@section scripts {
```<issue_comment>username_1: How about you pass the variable "i" as a query param and let your controller interpret it and use it as needed.
Something like this:
```
@Html.Partial("~/Views/Search/_MyPartialView.cshtml?elementNo=" + i)
```
You can pass the model MyMarkerObject as well and then you can process it as needed.

This is example for your code
Controller
```
[HttpPost]
public ActionResult MyPartialView( MyMarkerObject myMarkerObject )
{
return PartialView("~/Views/Search/_MyPartialView.cshtml", myMarkerObject );
}
//Javascript
$.ajax({
url: '@Url.Action("Search","MyPartialView")',
type: 'POST',
data: JSON.stringify(item),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
error: function (xhr) {
alert('Error: ' + xhr.statusText);
},
success: function (result) {
var infowindow = new google.maps.InfoWindow({
content: result
});
},
async: true,
processData: false
});

Inside this loop, I have `CellCount` which represent the number of the cell inside the Range, every 7 columns I reset the column number here:
```
Col = CellCount Mod 7 ' get the column number , every 7 columns reset the column
```
and add 1 to the Row here:
```
PasteRow = Int((CellCount - 1) / 7) + 1 ' get the row number
```
***Code***
```
Option Explicit
Sub CopyUpto7Columns()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim Rng As Range, C As Range
Dim LastRow As Long, CellCount As Long
Dim PasteRow As Long, Col As Long
Set ws1 = Sheets("F2")
Set ws2 = Sheets("List1")
With ws1
' get dynamic last row
LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
' set the range object in sheet "F2" up to column 31
Set Rng = .Range(.Cells(1, 1), .Cells(LastRow, 31))
End With
PasteRow = 1 ' start pasting from the first row
CellCount = 1 ' reset cell count in Range
' loop through range (cell by cell)
For Each C In Rng
PasteRow = Int((CellCount - 1) / 7) + 1 ' get the row number
Col = CellCount Mod 7 ' get the column number , every 7 columns reset the column
If Col = 0 Then Col = 7
ws2.Cells(PasteRow, Col).Value = C.Value
CellCount = CellCount + 1
Next C

2018/03/20 | 1,341 | 4,647 | <issue_start>username_0: I am using intel fortran 2016. I have defined some precision variables as follows:
```
! definition of single, double and quad precision
integer, parameter :: SINGLE_PRECISION = selected_real_kind(6, 37)
integer, parameter :: DOUBLE_PRECISION = selected_real_kind(15, 307) ! is used as standard precision
integer, parameter :: QUAD_PRECISION = selected_real_kind(33, 4931)
! definition of variable precision for REAL, INTEGER
integer, parameter :: REAL_TYPE = DOUBLE_PRECISION
integer, parameter :: INTEGER_TYPE = 4
```
I would like to now use these to control the precision of a parameter that gets declared in a subroutine as follows:
```
SUBROUTINE SKIP(IUNIT,NBYTS)
IMPLICIT DOUBLE PRECISION (A-H,O-Z)
Character c*1
Parameter(n1 = 1024, nT1 = 8*n1)
```
I tried the following :
```
Parameter(INTEGER_TYPE)((n1 = 1024, nT1 = 8*n1)
Parameter(INTEGER_TYPE)((n1 = 1024, nT1 = 8*n1, kind = INTEGER_TYPE)
```
All to no avail. What is the proper way to define parameter precision in Fortran?
Thanks<issue_comment>username_1: You can define a parameter of a specific kind with
```
TYPE, PARAMETER :: name = value_kind
```
So to define, say, an integer n1 with kind INTEGER\_TYPE you do
```
integer(kind=INTEGER_TYPE), parameter :: n1 = 1024_INTEGER_TYPE
```
Upvotes: 1 <issue_comment>username_2: You have an answer which gives the best way to specify the kind of a named constant. You can find much more detail around [this question](https://stackoverflow.com/q/838310/3157076).
However, I'll add some detail about the `parameter` statement.
The `parameter` statement makes an object a named constant and specifies its value. It doesn't specify the type or kind of that object.
The example of the question uses implicit typing for `n1` and `nT1`. These are implicitly default integer.
The implicit rule may be changed (I won't show how), but the type may also be given explicitly:
```
integer(INTEGER_TYPE) n1, nT1
parameter (n1=1024, nT1=8*n1)
```
Still, the form of the other answer is preferable. And, as noted there, the kind of the literal constants may also be given in the `parameter` statement if desired.
Upvotes: 1 <issue_comment>username_3: **Note:** this is essentially the same as [Francescalus' answer](https://stackoverflow.com/a/49379472/8344060), but with some extra fluf.
The issue at hand here is related to the `IMPLICIT` statement.
The [Fortran standard](https://j3-fortran.org/doc/year/10/10-007.pdf) makes the following statements :
>
> **5.5 IMPLICIT statement**
>
>
> 1. In a scoping unit, an `IMPLICIT` statement specifies a type, and
> possibly type parameters, for all implicitly typed data entities whose
> names begin with one of the letters specified in the statement.
> Alternatively, it may indicate that no implicit typing rules are to
> apply in a particular scoping unit.
> 2.
> 3. In each scoping unit, there is a mapping, which may be null, between
> each of the letters `A, B, ..., Z` and a type (and type parameters).
> An `IMPLICIT` statement specifies the mapping for the letters in its
> letter-spec-list. `IMPLICIT NONE` specifies the null mapping for all
> the letters. If a mapping is not specified for a letter, the
> default for a program unit or an interface body is default integer if
> the letter is `I, J`, ..., or `N` and default real otherwise, and the
> default for an internal or module procedure is the mapping in the host
> scoping unit.
>
>
>
So in short, by default everything is of type default `REAL` unless it starts with `I`,`J`,...,`N`, then it is of type default `INTEGER`.
In the example in the question, the variables `n1` and `nT1` are hence default `INTEGER` unless specified otherwise. Thus the following might be a solution :
```
subroutine skip(IUNIT,NBYTS)
implicit double precision (A-H,O-Z)
character c*1
integer(kind=integer_kind), parameter :: n1 = 1024, nT1 = 8*n1
...
end subroutine skip
```
As a general remark on variable declaration I would like to make the following remarks:
* use `implicit none` as default. It makes debugging easier
* avoid star notation, it is not part of the standard for anything but characters, and for characters it is declared obsolescent.
* make use of `kind` parameters declared in the intrinsic module `iso_fortran_env`
* be aware that `double precision` does not necessarily mean "double precision" in the literal or IEEE sense of the word. It just means, twice the storage of a `real` and a higher precision than `real`. (a higher precision could be one-digit).

Upvotes: 3 <issue_comment>username_2: This may work:
1. Bring down the network
2. Disable TLS in below files by commenting environment variables listed below.
```
base/docker-compose-base.yaml
base/peer-base.yaml
docker-compose-cli.yaml:
docker-compose-e2e-template.yam
```
ENV:
```
CORE_PEER_TLS_ENABLED
CORE_PEER_TLS_CERT_FILE
CORE_PEER_TLS_KEY_FILE
CORE_PEER_TLS_ROOTCERT_FILE
```
3. Bring up the network
Another way is to pass TLS certificate as an argument to peer fetch channel command.

Why does git gives this message, is there a way to tell it things are fine?<issue_comment>username_1: The behaviour is defined in the [documentation](https://git-scm.com/docs/git-cherry-pick).
What you need in your case is

Upvotes: 1 <issue_comment>username_2: It seems that you did a `cherry-pick` before, which failed due to conflicts. Thus, git thinks you're still in the middle of the cherry pick, since it expects you to fix conflicts, add conflicted files and run `git cherry-pick --continue`.
Your options here are to run `git cherry-pick --abort` which will abort the cherry pick, i.e. return the conflicted files to their previous state, possible losing changes, or to run `git cherry-pick --continue`, which will continue the cherry pick. When you do not remember when and what you did with the cherry-pick, this is probably the better option, althoough you should watch your repository closely before and after the `--continue` command.
Both commands will get you out of the cherry-pick state and allow you to perform the amend.
Upvotes: 3 <issue_comment>username_3: When running actions like `cherry-pick`, `rebase` or `merge`, `git` keeps track of several info on the base commit.
It looks like a reasonable safety to prevent the base commit from being modified.
---
I would advise you to somehow finish your `cherry-pick`, and then use `rebase -i` to modifiy the sequence of commits you want.
If we use the following names :
```
--*--*-- ... --A--B <- HEAD
\
*-- ... X <- cherry-picked commit
# you are currently on B, you run :
git cherry-pick X
```
If you wish to reach :
```
--*--*-- ... --A--B'--X' <- cherry-picked version of X
\ ^
\ a modified version of B
*-- ... X
```
you can :
```
# add the modifications intended for B' :
git add -p [files]
# create a regular commit, using "git commit" :
git commit
--*--*-- ... --A--B--C
# complete the cherry-pick process :
git add [files with solved conflicts]
git cherry-pick --continue
--*--*-- ... --A--B--C--X'
# use 'rebase -i A' to squash B and C into one commit
git rebase -i A
# set the rebase actions to "squash C into B"
# the result should be what you expect :
--*--*-- ... --A--B'--X'
```
Upvotes: 0 <issue_comment>username_4: I manually removed `.git/CHERRY_PICK_HEAD` now git doesn't know I did a cherry-pick, so amend works like it was a normal commit amend.
`cherry-pick --continue` adds a new commit message and would need to rebase which is a hassle.

I do not know how to create a date array for given fields<issue_comment>username_1: You may try to first load your data in an object tree and then use a json converter like [Json.Net](https://www.newtonsoft.com/json). But you need to have a consistent format for your data. A kind of thing like the code below :
```
class Data{
//to be more defined maybe a string could be a start
string value;
}
class Log{
string email;
string link;
List data;
}
List myLog = new List();
// load your "log" data into this list
string json = JsonConvert.SerializeObject(myLog);
```
Upvotes: 2 <issue_comment>username_2: A slightly different answer from the first answer.
Let's assume you already able to get the records from the database into this class.
```
public class Log
{
public string Email { get; set; }
public string Link { get; set; }
public string Data { get; set; }
}
```
You can then group the logs by email and link using the following LINQ syntax.
```
var logs = new List(); // The list should come from the records in the database.
var result = new
{
Log = logs.GroupBy(x => new { x.Email, x.Link })
.Select(y => new { y.Key.Email, y.Key.Link, Data = y.Select(z => z.Data) })
};
```
And use `Newtonsoft.Json` to serialize it.
```
var json = JsonConvert.SerializeObject(result);
```
